 * For Mono-based development (e.g. Unity) that requires full .NET framework, you need to set `"omnisharp.useGlobalMono": "always"`. The current value of "auto" will remain "never" until Mono [upgrades their bundled MSBuild version](https://github.com/mono/mono/issues/20250).
 * After selecting a solution filter (*.slnf) from the project selector, the solution's name will be displayed in the status bar instead of the filter's.
 * Known limitations with the preview Razor (cshtml) language service to be addressed in a future release:

   * Only ASP.NET Core projects are supported (no support for ASP.NET projects)
   * Error squiggles misaligned for expressions near the start of a new line
   * Emmet based abbreviation expansion is not yet supported (See note in readme for how to enable through your settings.json)

+  When this option is set to `true` a .NET 6 build of OmniSharp is downloaded and used for language services. This setting should only be used when working with newer SDK style projects and would be expected to fail when trying to load a Full Framework projects (such as Unity projects).

+  * if the option is set, the OmniSharp log should inlcude text like the following "OmniSharp server started with .NET 6.0.100" and "Registered MSBuild instance: .NET Core SDK 6.0.100 17.0.0 - "/usr/local/share/dotnet/sdk/6.0.100/". All language services should continue to work as expected when an SDK-style project is open.

   #### omnisharp.useGlobalMono (for Linux/Mac)
   This option can be set to any of the following values:
   * "auto" - Will launch OmniSharp using mono if version>=5.2.0 is installed but will launch using the run script if that is not so.
