- The Mac implementation does not have fallback logic like the windows variant because Workspaces in VS mac world are spun up / torn down regularly. We don't want to be tracking down bugs that involve us adding services or Razor logic to Workspaces that have nothing to do with Razor.
- Added a test for the `DefaultVisualStudioWorkspaceAccessor`. Could not add other tests due to limitations of MonoDevelop's abstractions.
