  * In a project that uses globbing (.NET Core), use the VS Code file explorer to add a new file next to the csproj. Intellisense/sighelp/etc should be available in the new file
  * Add a new file and reference a type in it from a different file. Deleting from disk the file containing the referenced type should produce error messages
  +#### Razor
  +The Razor experience is available when you open a .cshtml file in a valid OmniSharp project. To setup a test project to verify on you can do:
  +1. `dotnet new razor`
  +2. Open `Pages/Index.cshtml`
  +
  +##### C# Completion
  +* Typing `@DateTime.Now` and `@(DateTime.Now)` provides completions throughout typing.
  +* Completion is available for types that exist in the project (i.e. `Program`)
  +* Typing `@model DateTime` prompts for completion for the `model` symbol and the `DateTime` symbol.
  +
  +#### C# Signature Help
  +* Typing `@Html.Raw()` prompts for signature help inside of the `()`.
  +
  +#### C# Diagnostics
  +* Typing `@ThisDoesNotExist` results in an error being created and squiggled in the .cshtml file. NOTE: This error squiggly will be misaligned due to known issues.
  +
  +#### Razor Options
  +
  +##### razor.disabled
  +This option can be set to `true` to disable the above described C# experience.
  +
  +##### razor.languageServer.trace
  +This option should always be displayed in the View --> Output --> Razor Log window
  +This option can be set to any of the following values:
  + * "Off" - Will launch Razor Language server with its log output set to 'Off'. The header in the Razor Log output window will be shown but no other content will be shown.
  + * "Messages" - Will launch Razor Language server with its log output set to 'Messages'. Limited messages will be shown such as "Opening document xyz in project abc".
