Step 1: Add HostProject
This is a somewhat complex addition to the ProjectSnapshotManager. Now
that we accept updates from the underlying IDE project system we need to
coordinate those with the Workspace.
This means that ProjectSnapshot itself now also has a version concept.
Step 2: Introduce a new project system based on CPS
We use project capabilities defined by the Razor SDK to determine
whether to rely on MSBuild evaluation to detect the configuration or
whether to fallback to assembly-based detection.
Step 3: Flow RazorConfiguration everywhere
We use now expose the RazorConfiguration to the language service and
editor. This means that we no longer need to detect the project's
configuration asynchronously, it happens much faster now.
- Added `ILanguageServiceFactory` types for all serviceable contracts.
- Maintained binary compatibility by copy/pasting existing services into a Legacy folder.
- Added a Workspaces.Test project since their implementations moved.
- Updated binary incompatible version of `RazorSyntaxFactsService` to not depend on VisualStudio. Added an extension type to the VS.LanguageServices.Razor project to enable easy-access from VisualStudio.
Below on refers to the binary incompatible copies.
Core services that were **entirely** moved from VisualStudio.Razor => Razor.Workspaces are as follows:
- `RazorSyntaxFactsService`, this included mutating the API to not depend on VisualStudio and moving some primitive types such as `AcceptedCharacters`.
- `TagHelperCompletionService`
- `TagHelperFactsService`
These all have a `ServiceLayer` of `Editor`.
Bits that were partially moved:
- `RazorTemplateEngineFactoryService`. The Default implementation and its corresponding factory still live in VisualStudio.Razor. This way Razor.Workspaces can get by without a reference to Mvc.Razor.Extensions.
- `ITagHelperResolver` used to exist in VisualStudio.Razor. Removed the type and replaced its usage with the already-existing `TagHelperResolver` type in Razor.Workspaces. Both contracts were nearly identical.
These all have a `ServiceLayer` of `Default`.

- Replaced the magic strings with extension methods that produce the same behavior as the string keys did.
- Added tests to validate new extension methods.
#1307
- Removed all design time descriptors and put their API surface into their corresponding descriptor. Part of removing the design time API surface was removing the tracking of `<Remarks>`, it wasn't used so there's on need to track it until we need it.
- Removed the Type requirement from `TagHelperDescriptor`. With this separation we'll be able to have abstract `TagHelper`s that aren't based on a class implementation.
- Removed Prefix from the `TagHelperDescriptor` API surface. It was a legacy requirement based on how the Razor parser was put together. We can work around this now.
- Stripped correlation information from the immediate `TagHelperDescriptor` API surface. Instead this information is now tracked in `TagMatchingRule`s. This change means that you will not have multiple `TagHelperDescriptor`s per `TagHelper`; instead it's all tracked in a single descriptor. A side effect of this change was the transformation of `IsIndexer` => 3 new properties.
- Renamed many descriptor types and property names.
- Added builder APIs to construct TagHelpers since they're inherently immutable in their API surface.
- Added `ITagHelperDescriptorBuilder` to represent `TagHelper`s that are built from an `ITagHelper` implementing class. It re-introduces the `TypeName` association of a `TagHelper`.
- Added `ITagHelperBoundAttributeDescriptorBuilder` to represent that an attribute was associated with a property.
- Added validation methods to the descriptor builders to enable consumers to validate the current state of the builder and add diagnostics as necessary.
- Moved descriptors away from RazorError.
- Updated the various comparers to understand the descriptors new API.
- Added a new `RazorDiagnosticFactory` abstraction to handle `RazorDiagnostic`s and their corresponding errors/ids etc. This new API should allow for easy addition of new `RazorDiagnostic` errors.
- Updated the `DefaultTagHelperDescriptorFactory` to construct `TagHelperDescriptor`s using the new builder APIs and in the new descriptor format (1 descriptor per type).
- Updated `ViewComponentTagHelperDescriptorFactory` to construct `TagHelperDescriptor`s with the builder API.
- With both factory implementations code was duplicated because the ViewComponent work will be moving outside of Razor once we have the proper hooks.
- Updated `TagHelper` binding bits to capture a binding result in order to query which rules appy to a given tag name.
Addressed feedback
- Update tests to react to new `TagHelperDescriptor` API.
- Remove case sensitive comparers and some cleanup
- Added TagHelperDescriptorJsonConverter, RazorDiagnosticJsonConverter and added serialization tests
- Decided to not expose the resolutions errors in the Razor extension. If we feel that it's good debug information we can add it later.
- Added a `TagHelperResolutionResult` type to Razor.Workspaces so it can be used in the language and remote service.
