 ASP.NET Core
 ============
 
-ASP.NET Core is an open-source and cross-platform framework for building modern cloud based internet connected applications, such as web apps, IoT apps and mobile backends. ASP.NET Core apps can run on .NET Core or on the full .NET Framework. It was architected to provide an optimized development framework for apps that are deployed to the cloud or run on-premises. It consists of modular components with minimal overhead, so you retain flexibility while constructing your solutions. You can develop and run your ASP.NET Core apps cross-platform on Windows, Mac and Linux. [Learn more about ASP.NET Core](https://docs.microsoft.com/aspnet/core/).

+# Issue Management Policies
+
+We have a lot of issue traffic to manage, so we have a few policies in place to help us do that. This is a brief summary of some of the policies we have in place and the justification for them.
+
+## Commenting on closed issues
+
+In general, we recommend you open a new issue if you have a bug, feature request, or question to discuss. If you find a closed issue that is related, open a *new issue* and link to the closed issue rather than posting on the closed issue. Closed issues don't appear in our triage process, so only the people who have been active on the original thread will be notified of your comment. A new issue will get more attention from the team.
+
+*In general* we don't mind getting duplicate issues. It's easier for us to close duplicate issues than to discuss multiple root causes on a single issue! We may close your issue as a duplicate if we determine it has the same root cause as another. Don't worry! It's not a waste of our time!
+
+## Needs Author Feedback
+
+If a contributor reviews an issue and determines that more information is needed from the author, they will post a comment requesting that information and apply the `Needs: Author Feedback` label. This label indicates that the author needs to post a response in order for us to continue investigating the issue.
+
+If the author does not post a response within **7 days**, the issue will be automatically closed. If the author responds within **7 days** after the issue is closed, the issue will be automatically re-opened. We recognize that you may not be able to respond immediately to our requests, we're happy to hear from you whenever you're able to provide the new information.
+
+## Duplicate issues
+
+If we determine that the issue is a duplicate of another, we will label it with the `Resolution: Duplicate` label. The issue will be automatically closed in 1 day of inactivity.
+
+## Answered questions
+
+If we determine that the issue is a question and have posted an answer, we will label it with the `Resolution: Answered` label. The issue will be automatically closed in 1 day of inactivity.
+
+## Locking closed issues
+
+After an issue has been closed and had no activity for **30 days** it will be automatically locked as *resolved*. This is done in order to reduce confusion as to where to post new comments. If you are still encountering the problem reported in an issue, or have a related question or bug report, feel free to open a *new issue* and link to the original (now locked) issue!

 # Microsoft.AspNetCore.Authentication.Certificate
- 
-This project sort of contains an implementation of [Certificate Authentication](https://tools.ietf.org/html/rfc5246#section-7.4.4) for ASP.NET Core. 
-Certificate authentication happens at the TLS level, long before it ever gets to ASP.NET Core, so, more accurately this is an authentication handler
-that validates the certificate and then gives you an event where you can resolve that certificate to a ClaimsPrincipal. 
 
-You **must** [configure your host](#hostConfiguration) for certificate authentication, be it IIS, Kestrel, Azure Web Applications or whatever else you're using.
-
-## Getting started
-
-First acquire an HTTPS certificate, apply it and then [configure your host](#hostConfiguration) to require certificates.
-
-In your web application add a reference to the package, then in the `ConfigureServices` method in `startup.cs` call
-`app.AddAuthentication(CertificateAuthenticationDefaults.AuthenticationScheme).UseCertificateAuthentication(...);` with your options, 
-providing a delegate for `OnValidateCertificate` to validate the client certificate sent with requests and turn that information 
-into an `ClaimsPrincipal`, set it on the `context.Principal` property and call `context.Success()`.
-
-If you change your scheme name in the options for the authentication handler you need to change the scheme name in 
-`AddAuthentication()` to ensure it's used on every request which ends in an endpoint that requires authorization.
-
-If authentication fails this handler will return a `403 (Forbidden)` response rather a `401 (Unauthorized)` as you
-might expect - this is because the authentication should happen during the initial TLS connection - by the time it 
-reaches the handler it's too late, and there's no way to actually upgrade the connection from an anonymous connection 
-to one with a certificate.
-
-You must also add `app.UseAuthentication();` in the `Configure` method, otherwise nothing will ever get called.
-
-For example;
-
-```c#
-public void ConfigureServices(IServiceCollection services)
-{
-    services.AddAuthentication(CertificateAuthenticationDefaults.AuthenticationScheme)
-            .AddCertificate();
-    // All the other service configuration.
-}
-
-public void Configure(IApplicationBuilder app, IHostingEnvironment env)
-{
-    app.UseAuthentication();
-
-    // All the other app configuration.
-}
-```
-
-In the sample above you can see the default way to add certificate authentication. The handler will construct a user principal using the common certificate properties for you.
-
-## Configuring Certificate Validation
-
-The `CertificateAuthenticationOptions` handler has some built in validations that are the minimium validations you should perform on 
-a certificate. Each of these settings are turned on by default.
-
-### ValidateCertificateChain
-
-This check validates that the issuer for the certificate is trusted by the application host OS. If 
-you are going to accept self-signed certificates you must disable this check.
-
-### ValidateCertificateUse
-
-This check validates that the certificate presented by the client has the Client Authentication 
-extended key use, or no EKUs at all (as the specifications say if no EKU is specified then all EKUs 
-are valid). 
-
-### ValidateValidityPeriod
-
-This check validates that the certificate is within its validity period. As the handler runs on every 
-request this ensures that a certificate that was valid when it was presented has not expired during
-its current session.
-
-### RevocationFlag
-
-A flag which specifies which certificates in the chain are checked for revocation.
-
-Revocation checks are only performed when the certificate is chained to a root certificate.
-
-### RevocationMode 
-
-A flag which specifies how revocation checks are performed.
-Specifying an on-line check can result in a long delay while the certificate authority is contacted.
-
-Revocation checks are only performed when the certificate is chained to a root certificate.
-
-### Can I configure my application to require a certificate only on certain paths?
-
-Not possible, remember the certificate exchange is done that the start of the HTTPS conversation, 
-it's done by the host, not the application. Kestrel, IIS, Azure Web Apps don't have any configuration for
-this sort of thing.
-
-# Handler events
-
-The handler has two events, `OnAuthenticationFailed()`, which is called if an exception happens during authentication and allows you to react, and `OnValidateCertificate()` which is 
-called after certificate has been validated, passed validation, abut before the default principal has been created. This allows you to perform your own validation, for example 
-checking if the certificate is one your services knows about, and to construct your own principal. For example,
-
-```c#
-services.AddAuthentication(CertificateAuthenticationDefaults.AuthenticationScheme)
-        .AddCertificate(options =>
-        {
-            options.Events = new CertificateAuthenticationEvents
-            {
-                OnValidateCertificate = context =>
-                {
-                    var claims = new[]
-                    {
-                        new Claim(ClaimTypes.NameIdentifier, context.ClientCertificate.Subject, ClaimValueTypes.String, context.Options.ClaimsIssuer),
-                        new Claim(ClaimTypes.Name, context.ClientCertificate.Subject, ClaimValueTypes.String, context.Options.ClaimsIssuer)
-                    };
-
-                    context.Principal = new ClaimsPrincipal(new ClaimsIdentity(claims, context.Scheme.Name));
-                    context.Success();
-
-                    return Task.CompletedTask;
-                }
-            };
-        });
-```
-
-If you find the inbound certificate doesn't meet your extra validation call `context.Fail("failure Reason")` with a failure reason.
-
-For real functionality you will probably want to call a service registered in DI which talks to a database or other type of 
-user store. You can grab your service by using the context passed into your delegates, like so
-
-```c#
-services.AddAuthentication(CertificateAuthenticationDefaults.AuthenticationScheme)
-        .AddCertificate(options =>
-        {
-            options.Events = new CertificateAuthenticationEvents
-            {
-                OnCertificateValidated = context =>
-                {
-                    var validationService =
-                        context.HttpContext.RequestServices.GetService<ICertificateValidationService>();
-                    
-                    if (validationService.ValidateCertificate(context.ClientCertificate))
-                    {
-                        var claims = new[]
-                        {
-                            new Claim(ClaimTypes.NameIdentifier, context.ClientCertificate.Subject, ClaimValueTypes.String, context.Options.ClaimsIssuer),
-                            new Claim(ClaimTypes.Name, context.ClientCertificate.Subject, ClaimValueTypes.String, context.Options.ClaimsIssuer)
-                        };
-
-                        context.Principal = new ClaimsPrincipal(new ClaimsIdentity(claims, context.Scheme.Name));
-                        context.Success();
-                    }                     
-
-                    return Task.CompletedTask;
-                }
-            };
-        });
-```
-Note that conceptually the validation of the certification is an authorization concern, and putting a check on, for example, an issuer or thumbprint in an authorization policy rather 
-than inside OnCertificateValidated() is perfectly acceptable.
-
-## <a name="hostConfiguration"></a>Configuring your host to require certificates
-
-### Kestrel
-
-In program.cs configure `UseKestrel()` as follows.
-
-```c#
-public static IWebHost BuildWebHost(string[] args)
-    => WebHost.CreateDefaultBuilder(args)
-    .UseStartup<Startup>()
-    .ConfigureKestrel(options =>
-    {
-        options.ConfigureHttpsDefaults(opt =>
-        {
-            opt.ClientCertificateMode = ClientCertificateMode.RequireCertificate;
-        });
-    })
-    .Build();
-```
-You must set the `ClientCertificateValidation` delegate to `CertificateValidator.DisableChannelValidation` in order to stop Kestrel using the default OS certificate validation routine and, 
-instead, letting the authentication handler perform the validation.
-
-### IIS
-
-In the IIS Manager 
-
-1. Select your Site in the Connections tab.
-2. Double click the SSL Settings in the Features View window.
-3. Check the `Require SSL` Check Box and select the `Require` radio button under Client Certificates.
-
-![Client Certificate Settings in IIS](README-IISConfig.png "Client Certificate Settings in IIS")
-
-### Azure
-
-See the [Azure documentation](https://docs.microsoft.com/en-us/azure/app-service/app-service-web-configure-tls-mutual-auth) 
-to configure Azure Web Apps then add the following to your application startup method, `Configure(IApplicationBuilder app)` add the 
-following line before the call to `app.UseAuthentication();`
-
-```c#
-app.UseCertificateHeaderForwarding();
-```
-
-### Random custom web proxies
-
-If you're using a proxy which isn't IIS or Azure's Web Apps Application Request Routing you will need to configure your proxy
-to forward the certificate it received in an HTTP header. 
-In your application startup method, `Configure(IApplicationBuilder app)`, add the 
-following line before the call to `app.UseAuthentication();`
-
-```c#
-app.UseCertificateForwarding();
-```
-
-You will also need to configure the Certificate Forwarding middleware to specify the header name.
-In your service configuration method, `ConfigureServices(IServiceCollection services)` add 
-the following code to configure the header the forwarding middleware will build a certificate from;
-
-```c#
-services.AddCertificateForwarding(options =>
-{
-    options.CertificateHeader = "YOUR_CUSTOM_HEADER_NAME";
-});
-```
-
-Finally, if your proxy is doing something weird to pass the header on, rather than base 64 encoding it 
-(looking at you nginx (╯°□°）╯︵ ┻━┻) you can override the converter option to be a func that will
-perform the optional conversion, for example 
-
-```c#
-services.AddCertificateForwarding(options =>
-{
-    options.CertificateHeader = "YOUR_CUSTOM_HEADER_NAME";
-    options.HeaderConverter = (headerValue) => 
-    {
-        var clientCertificate = 
-           /* some weird conversion logic to create an X509Certificate2 */
-        return clientCertificate;
-    }
-});
-```
+This project sort of contains an implementation of [Certificate Authentication](https://tools.ietf.org/html/rfc5246#section-7.4.4) for ASP.NET Core. Certificate authentication happens at the TLS level, long before it ever gets to ASP.NET Core, so, more accurately this is an authentication handler that validates the certificate and then gives you an event where you can resolve that certificate to a ClaimsPrincipal.
 
+For more information, see [Configure certificate authentication in ASP.NET Core](https://docs.microsoft.com/aspnet/core/security/authentication/certauth).

 Cross Machine Tests
 
-Kerberos can only be tested in a multi-machine environment. On localhost it always falls back to NTLM which has different requirements.  Multi-machine is also neccisary for interop testing across OSs. Kerberos also requires domain controler SPN configuration so we can't test it on arbitrary test boxes.
+Kerberos can only be tested in a multi-machine environment. On localhost it always falls back to NTLM which has different requirements.  Multi-machine is also necessary for interop testing across OSs. Kerberos also requires domain controller SPN configuration so we can't test it on arbitrary test boxes.
 
 Test structure:
 - A remote test server with various endpoints with different authentication restrictions.
-- A remote test client with endpoints that execute specific scenarios. The input for these endpoints is theory data. The output is either 200Ok, or a failure code and desciption.
+- A remote test client with endpoints that execute specific scenarios. The input for these endpoints is theory data. The output is either 200Ok, or a failure code and description.
 - The CrossMachineTest class that drives the tests. It invokes the client app with the theory data and confirms the results.
 
-We use these three components beceause it allows us to run the tests from a dev machine or CI agent that is not part of the dedicated test domain/environment.
+We use these three components because it allows us to run the tests from a dev machine or CI agent that is not part of the dedicated test domain/environment.
 
 (Static) Environment Setup:
 - Warning, this environment can take a day to set up. That's why we want a static test environment that we can re-use.
 - Create a Windows server running DNS and Active Directory. Promote it to a domain controller.
   - Create an SPN on this machine for Windows -> Windows testing. `setspn -S "http/chrross-dc.crkerberos.com" -U administrator`
   - Future: Can we replace the domain controller with an AAD instance? We'd still want a second windows machine for Windows -> Windows testing, but AAD might be easier to configure.

+## Using MsQuic on Windows
+
+### Setup pre-requisites
+
+1. Update machine to the latest Windows Insiders build (build number 19010 or later). This is required for TLS 1.3 support.
+2. Copy msquic.dll and msquic.pdb to this directory and uncomment the copy task in Microsoft.AspNetCore.Server.Kestrel.Transport.MsQuic.csproj. This will copy the msquic.dll into any built project.
+
+For external contributors, msquic.dll isn't available publicly yet. See https://github.com/aspnet/Announcements/issues/393.
+
+Credit to Diwakar Mantha and the Kaizala team for the MsQuic interop code.

+  <!-- 
+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+## Http2Cat
+
+Http2Cat is a low level Http2 testing framework designed to excersize a server with frame level control. This can be useful for unit testing and compat testing.
+
+The framework is distributed as internal sources since it shares the basic building blocks from Kestrel's Http2 implementation (frames, enum flags, frame reading and writing, etc.). InternalsVisibleTo should not be used, any needed components should be moved to one of the shared code directories.
+
+This Http2Cat folder contains non-production code used in the test client. The shared production code is kept in separate folders.

+  <!-- 
+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

 - Create an .npmrc file with the following line:
-  `@aspnet:registry=https://dotnet.myget.org/f/aspnetcore-dev/npm/`
+  `@microsoft:registry=https://dotnet.myget.org/f/aspnetcore-dev/npm/`
 - Run:

 Alternatively, if you don't want to create the .npmrc file run the following commands:
 ```
-npm install @aspnet/signalr --registry https://dotnet.myget.org/f/aspnetcore-dev/npm/
+npm install @microsoft/signalr --registry https://dotnet.myget.org/f/aspnetcore-dev/npm/

 We also have a MsgPack protocol library which is installed via:
 
 ```bash
-npm install @aspnet/signalr-protocol-msgpack
+npm install @microsoft/signalr-protocol-msgpack
 ```
 
 ## Deploying
 
-Once you've installed the NPM modules, they will be located in the `node_modules/@aspnet/signalr` and `node_modules/@aspnet/signalr-protocol-msgpack` folders. If you are building a NodeJS application or using an ECMAScript module loader/bundler (such as [webpack](https://webpack.js.org)), you can load them directly. If you are building a browser application without using a module bundler, you can find UMD-compatible bundles in the `dist/browser` folder; minified versions are provided as well. Simply copy these to your project as appropriate and use a build task to keep them up-to-date.

+Throughout this document, the term `[endpoint-base]` is used to refer to the route assigned to a particular end point. The terms `connection-id` and `connectionToken` are used to refer to the connection ID and connection token provided by the `POST [endpoint-base]/negotiate` request.
 
 **NOTE on errors:** In all error cases, by default, the detailed exception message is **never** provided; a short description string may be provided. However, an application developer may elect to allow detailed exception messages to be emitted, which should only be used in the `Development` environment. Unexpected errors are communicated by HTTP `500 Server Error` status codes or WebSockets non-`1000 Normal Closure` close frames; in these cases the connection should be considered to be terminated.
 
 ## `POST [endpoint-base]/negotiate` request
 
-The `POST [endpoint-base]/negotiate` request is used to establish a connection between the client and the server. The content type of the response is `application/json`. The response to the `POST [endpoint-base]/negotiate` request contains one of three types of responses:
+The `POST [endpoint-base]/negotiate` request is used to establish a connection between the client and the server.
 
-1. A response that contains the `connectionId` which will be used to identify the connection on the server and the list of the transports supported by the server.
+In the POST request the client sends a query string parameter with the key "negotiateVersion" and the value as the negotiate protocol version it would like to use. If the query string is omitted, the server treats the version as zero. The server will include a "negotiateVersion" property in the json response that says which version it will be using. The version is chosen as described below:
+* If the servers minimum supported protocol version is greater than the version requested by the client it will send an error response and close the connection
+* If the server supports the request version it will respond with the requested version
+* If the requested version is greater than the servers largest supported version the server will respond with its largest supported version
+The client may close the connection if the "negotiateVersion" in the response is not acceptable.
 
+The content type of the response is `application/json` and is a JSON payload containing properties to assist the client in establishing a persistent connection. Extra JSON properties that the client does not know about should be ignored. This allows for future additions without breaking older clients.
+
+### Version 1
+
+When the server and client agree on version 1 the server response will include a "connectionToken" property in addition to the "connectionId" property. The value of the "connectionToken" property will be used in the "id" query string for the HTTP requests described below, this value should be kept secret.
+
+A successful negotiate response will look similar to the following payload:
+  ```json
+  {
+    "connectionToken":"05265228-1e2c-46c5-82a1-6a5bcc3f0143",

+        "transport": "LongPolling",
+        "transferFormats": [ "Text", "Binary" ]
+      }
+    ]
+  }
+  ```
+
+  The payload returned from this endpoint provides the following data:
+
+  * The `connectionToken` which is **required** by the Long Polling and Server-Sent Events transports (in order to correlate sends and receives).
+  * The `connectionId` which is the id by which other clients can refer to it.
+  * The `negotiateVersion` which is the negotiation protocol version being used between the server and client.
+  * The `availableTransports` list which describes the transports the server supports. For each transport, the name of the transport (`transport`) is listed, as is a list of "transfer formats" supported by the transport (`transferFormats`)
+
+### Version 0

 * `id` (Required) - The Connection ID of the destination connection.
 
 When data is available, the server responds with a body in one of the two formats below (depending upon the value of the `Accept` header). The response may be chunked, as per the chunked encoding part of the HTTP spec.
 
 If the `id` parameter is missing, a `400 Bad Request` response is returned. If there is no connection with the ID specified in `id`, a `404 Not Found` response is returned.

 ## Commands
 
+### server
+
+The `server` command runs a web host exposing a single SignalR `Hub` endpoint on `/echo`.  After the first client connection, the server will periodically write concurrent connection information to the console.
+
+```
+> dotnet run -- help server
+
+Usage:  server [options]
+
+Options:
+  --log <LOG_LEVEL>                                     The LogLevel to use.
+  --azure-signalr-connectionstring <CONNECTION_STRING>  Azure SignalR Connection string to use
+  
+```
+
+Notes:
+
+* `LOG_LEVEL` switches internal logging only, not concurrent connection information, and defaults to `LogLevel.None`.  Use this option to control Kestrel / SignalR Warnings & Errors being logged to console.

 ### local
 
 The `local` command launches a set of local worker clients to establish connections to your SignalR server.
