v1.23.0

• Fix typo in supressBuildAssetsNotification setting name (#3941, PR: #3942)
• Introduced a new /quickinfo endpoint to provide a richer set of information compared to /typeinfo. Consumers are encouraged to use it as their hover provider (omnisharp-roslyn#1808, PR: omnisharp-roslyn#1860
• Added support for Roslyn EmbeddedLanguageCompletionProvider which enables completions for string literals for DateTime and Regex (omnisharp-roslyn#1871)
• Improve performance of the textDocument/codeAction request. (PR: omnisharp-roslyn#1814)
• Provide a warning when the discovered MSBuild version is lower than the minimumMSBuildVersion supported by the configured SDK (PR: omnisharp-roslyn#1875)
• Use the real MSBuild product version during discovery (PR: omnisharp-roslyn#1876)
• Fixed debugging in .NET 5 preview SDKs (#3459, PR: omnisharp-roslyn#1862)
• Move omnisharp vscode to the new hover implementation (#3928)
• Ignore screen size is bogus errors with ps (#3580, PR: #3961)
• Fix all providers support (PR: #3440, PR: omnisharp-roslyn#1581)
• Fix MSBuild version mismatch with new SDKs (omnisharp-vscode#3951, PR: #1883)

Note about using .NET Core 3.1.401 or .NET 5 Preview 8 SDKs on Mono platforms

Because of the new minimum MSBuild version requirement of these new SDKs, it will be necessary to use the Mono packaged with the C# extension. You can set "omnisharp.useGlobalMono" to "never" in the VS Code settings to force the use of the included Mono.

v1.22.0

If you enable our semantic highlighting support then, be sure to try out our new Visual Studio 2019 Light and Dark themes. TypeScript looks great in it too!

NOTE: For semantic highlighting ensure that editor.semanticHighlighting.enabled and csharp.semanticHighlighting.enabled are set to true.

Changes

• Add setting for enabling go to decompilation (PR: #3774)
• Add experimental Semantic Highlighter csharp.semanticHighlighting.enabled (#3565, PR: #3667
• Add commands for Run and Debug Tests in Context (PR: #3772, PR: omnisharp-roslyn/#1782)
• Do not add references CodeLens to Dispose methods (#3243, PR: #3780)
• Add Visual Studio 2019 themes with semantic colors (PR: #3790)
• Added support for WarningsAsErrors in csproj files (PR: omnisharp-roslyn/#1779)
• Added support for WarningsNotAsErrors in csproj files (omnisharp-roslyn/#1681, PR: #1784)
• Improved MSBuild scoring system (omnisharp-roslyn/#1783, PR: omnisharp-roslyn/#1797)
• Updated OmniSharp.Extensions.LanguageServer to 0.14.2 to fix synchronisation (PR: omnisharp-roslyn/#1791)
• Add test discovery and NoBuild option to test requests (PR: omnisharp-roslyn/#1719)
• Updated Razor support
  • Enable Semantic Highlighting for Razor TagHelpers and Blazor components (aspnetcore#21713)
  • Directive and TagHelper Attribute Completions are now committed contextually with =, : and commit characters. (aspnetcore#21485)
  • Removed TagHelper attribute completion snippet support as we felt the typing experience was superior without it.
• Add support for Blazor WebAssembly-specific debug adapter (dotnet/aspnetcore-tooling#1885)

v1.21.19-beta3

If you enable our semantic highlighting support then, be sure to try out our new Visual Studio 2019 Light and Dark themes. TypeScript looks great in it too!

Known issues

• Experimental Semantic Highlighter does not support razor files (.cshtml or .razor)

Changes in Beta 3

• Do not add references CodeLens to Dispose methods (#3243, PR: #3780)
• Add Visual Studio 2019 themes with semantic colors (PR: #3790)

• Added support for WarningsNotAsErrors in csproj files (omnisharp-roslyn/#1681, PR: #1784)
• Improved MSBuild scoring system (omnisharp-roslyn/#1783, PR: omnisharp-roslyn/#1797)

Changes in Beta 2

• Add commands for Run and Debug Tests in Context (PR: #3772, PR: omnisharp-roslyn/#1782)

Changes in Beta 1

v1.21.19-beta2

Known issues

• Experimental Semantic Highlighter does not support razor files (.cshtml or .razor)

Changes in Beta 2

• Add commands for Run and Debug Tests in Context (PR: #3772, PR: omnisharp-roslyn/#1782)

NOTE: These new commands require the latest builds of OmniSharp. You must set "omnisharp.path": "latest" in your settings.json. When 1.21.19 ships it will include a compatible version of OmniSharp.

Changes in Beta 1

• Add setting for enabling go to decompilation omnisharp.enableDecompilationSupport (PR: #3774)
• Add experimental Semantic Highlighter csharp.semanticHighlighting.enabled (#3565, PR: #3667

NOTE: Both settings are defaulted to false. For semantic highlighting ensure that editor.semanticHighlighting.enabled is also set to true.

Below are some suggested theme tweaks for Semantic Classification if you are used to Visual Studio 2019 enhanced colors and are using the Dark+ or Light+ themes.

v1.21.19-beta1

Known issues

• Experimental Semantic Highlighter does not support razor files (.cshtml or .razor)

Changes

• Add setting for enabling go to decompilation omnisharp.enableDecompilationSupport (PR: #3774)
• Add experimental Semantic Highlighter csharp.semanticHighlighting.enabled (#3565, PR: #3667

Both settings are defaulted to false.

For semantic highlighting ensure that editor.semanticHighlighting.enabled is also set to true.

Below are some suggested theme tweaks for Semantic Classification if you are used to Visual Studio 2019 enhanced colors and are using the Dark+ or Light+ themes.
