/// Defines the LSP server for Razor C#.  This is separate so that we can
/// activate this outside of a liveshare session and publish diagnostics

/// <remarks>
/// This specifies RunOnHost because in LiveShare we don't want this to activate on the guest instance
/// because LiveShare drops the ClientName when it mirrors guest clients, so this client ends up being
/// activated solely by its content type, which means it receives requests for normal .cs and .vb files
/// even for non-razor projects, which then of course fails because it gets text sync info for documents
/// it doesn't know about.
