What's new in 1.21.11

Updated the bundled to Mono 6.8.0 and MSBuild to be copied from Mono 6.8.0 (omnisharp-roslyn/#1693, PR: omnisharp-roslyn/#1697)
Included NugetSDKResolver in the minimal MSBuild, which introduces support for Nuget based project SDKs like Arcade (omnisharp-roslyn/#1678, PR: omnisharp-roslyn/#1696)

What's new in 1.21.10

Updated Razor support (PR:#3524)
- Added quick info (hover) support for TagHelper and Blazor components. You can now hover over TagHelpers, Components and their attributes to understand what associated C# type you're hovering over in addition to an attributes expected value type.
- Migrated Razor's project understanding from the VSCode extension into the Language Server. This enables the language server to reboot without extra assistance (reliability) from an LSP client and also enables future Razor LSP clients to have richer functionality with less "work".
- Added C# light bulbs to enable users to "Fully Qualify" members that are causing errors.
- Expanded Razor's TextMate grammar colorization support to understand email addresses and await foreach.
- Several bug fixes
Updated Debugger support (PR:#3515)
- Added option to search the NuGet.org Symbol Server
- Added options to control logging Process and Thread exits while debugging
Fixed a bug where completion items didn't decode symbols corectly (impacted, for example, object initializer completion quality) (#3465, PR:omnisharp-roslyn/#1670)
Updated to MsBuild 16.4.0 on Linux/MacOS (PR:omnisharp-roslyn/#1669)
Added support for implement type options - it is now possible to define whether code-fix/refactoring generated properties should be auto- or throwing-properties and at which place in the class should newly generated members be inserted. They can be set via OmniSharp configuration, such as omnisharp.json file. (PR: omnisharp-roslyn/#1672)
Added support for organizing usings on format. This can be set via OmniSharp configuration, such as omnisharp.json file. (PR:omnisharp-roslyn/#1686)

Do not set mono paths when running in standalone mode (omnisharp-vscode#3410, omnisharp-vscode#3340, omnisharp-roslyn/#1650, PR:omnisharp-roslyn/#1656)
Fixed a bug where OmniSharp would crash on startup if the path contained = sign (omnisharp-vscode#3436, PR:omnisharp-roslyn/#1661)
