This change adds an actual background worker for listening to project
change notifications and starts sending updates when the project's razor
dependencies change.
I had to do a litle surgery to get things working. There were plenty of
small bug fixes.
Additionally I got rid of the WeakReferences for tracking listeners. I
was seeing TextBuffers hanging around in VS longer than I expected and
the WeakReferences weren't getting cleaned up. I think it's better that
we just track the lifetime.
I've stripped out some of the dead code and complexity from the document
tracker in an attempt to simplify it. I will bring this back as part of
the multi-targeting work.
- 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`.
#1260
This is a MEF service that can actively or passively track open ITextViews
and give us information about the Razor initialization state and eventing
when it changes.
The purpose of this is to act as a bridge between the VS mef world and the
roslyn world.
For now this doesn't do any passive tracking of Razor documents, it's only
on demand. That means it will only be initialized and used right now when
you are using the Razor developer tools. This is just to reduce our risk,
it's not ideal to ship code in VS that's doing something without anyone
looking at the result.
