These are defined in [`VSServerCapabilities`](#vsservercapabilities) and can be communicated to the client in the [`InitializeResult.capabilities`](https://microsoft.github.io/language-server-protocol/specifications/specification-3-17/#initializeResult) field of the [`initialize`](https://microsoft.github.io/language-server-protocol/specifications/specification-3-17/#initialize) request.

Add a reference to these packages into the language server csproj file (and, if necessary, into the Visual Studio extension csproj file) using the latest package version available on NuGet:

 When using this package in a language server, configure the `JsonSerializer` using `VSExtensionUtilities.AddVSExtensionConverters` in order to allow extensions classes to be correctly deserialized. For example, this allows the `JsonSerializer` to correctly deserialize the [`CodeAction.Diagnostics`](https://microsoft.github.io/language-server-protocol/specifications/specification-3-17/#codeAction) entries of a [`codeAction/resolve`](https://microsoft.github.io/language-server-protocol/specifications/specification-3-17/#codeAction_resolve) request into [`VSDiagnostic`](#vsdiagnostic) objects even if [`CodeAction.Diagnostics`](https://microsoft.github.io/language-server-protocol/specifications/specification-3-17/#codeAction) is defined as an array of [`Diagnostic`](https://microsoft.github.io/language-server-protocol/specifications/specification-current/#diagnostic) objects.
