The project snapshot now maintains a RazorProjectEngine as well as set
of Tag Helpers that are known for that snapshot.
Pivoted some more services to be snapshot-centric.
Also added the ability to track .cshtml documents to the project system.
For now most components just ignore document changes.
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.
* Add prelimianry support for extensions to Razor
This PR adds MSBuild insfrastructure to the SDK that can understand
concepts we need to expose to the project, code generator and runtime
like:
- Language version
- Configuration
- Extensions (plugins)
As an example of how this works, I've done the wireup for MVC. This will
now generate assembly attributes in your application that can act as a
source-of-truth for what should be included in runtime compilation, and
it's all based on the project-file. This means that it can be delivered
and configured by packages.
The next step here is to implement a loader for RazorProjectEngine based
on these primitives, and then use it in our CLI tools and MVC.
The next step after that is to expose it in VS and VS4Mac through the
project system.
(cherry picked from commit 5b28c06d64)
- Restructured RazorLanguageVersion to be a sealed concrete type to enable things like `RazorLanguageVersion.Latest`; it also allows us to make broader changes in the future. Also, in the future if we want to add support for overriding operators to enable greater than comparisons we can as well.
- Removed version validity checks because we restrict who can construct a `RazorLanguageVersion` now. This way we don't have to check for valid versions all throughout our code.
- Added a simple `ProjectExtensibilityConfiguration` => `RazorLanguageVersion` method in the `DefaultProjectExtensibilityConfigurationFactory` to temporarily enable letting the system operate on the `RazorLanguageVersion`. Eventually that entire class will change.
