- The goal here is to enable components that use hosting abstractions to use
the web host. It lets us start to decouple components from the web host abstractions
where possible while not breaking any existing components. This will allow things
to work in both the generic host and the web host. The one snafu is the WebHostBuilderContext
which has an IHostingEnvironment typed as the AspNetCore.Abstractions type.
- Updated tests.

* Add IStartupConfigureServicesFilter to wrap ConfigureServices.
* Add IStartupConfigureContainerFilter<TContainerBuilder> to wrap
ConfigureContainer.
* Make StartupLoader build a thunk for configure services that
resolves all instances of IStartupConfigureServicesFilter and
IStartupConfigureContainerFilter<TContainerBuilder> and wraps
invocations to ConfigureServices and ConfigureContainer respectively.
* Refactor building the ConfigureServices callback into a private
builder class due to the increased complexity in the process.
* Create a scoped service provider for the call to Configure
- This allows scoped dependencies to be injected into the Configure method.
It means you can resolve the DbContext or any other scoped service without
the hassle of the CreateScope boiler plate. As a side effect, it also makes
Startup.Configure a bit more testable.
- Keep all the code in the test itself, instead of in an
extension method. Makes it easier to understand what's
happening without having to look up the extension
method's definition.
* Add support for executing IHostingStartup in specified assemblies
- Assemblies that are specified in the "hostingStartupAssemblies" configuration (; delimited)
setting can specify assemblies that use an assembly level attribute (HostingStartupAttribute)
to specify a type that implements IHostingStartup. This allows hosting environments to
extend the IWebHostBuilder with platform specific behavior before the application runs.
- Added tests
- Log errors that occur during load and execution of the IHostingStartup
when capture startup errors is off. This happens on start of the application.
- Added debug logging on startup to print out the hosted startup assemblies hosting
processed
