This automatically registers them on the JsonRpc object.
     1. `MutatesSolutionState` should be `true` for Handlers like `textDocument/didChange` which change solution state because this affects the queuing behavior required in order to ensure that the correct document version is being operated on.
     1. `HandleNotificationAsync` and `HandleRequestAsync`. These implement your actual handler behavior but it's very important that if they require access to the current state of a TextDocument that this information be gathered by `IRequestContextFactory` and put on the `RequestContext` object rather than retrieved here. If you fail to follow this stipulation you may run into document sync issues because requests which mutate document state are not guaranteed to happen in a particular order. This means that document state might change while your `HandleRequestAsync` request is executing, but the `IRequestContextFactory` is guaranteed to operate in a thread-safe manner.
 
 ## More complex examples
 
 - [Roslyn](https://github.com/dotnet/roslyn/tree/main/src/Features/LanguageServer/Protocol) is the original implementor of CLaSP.
-  - [`AbstractLanguageServer`](https://github.com/dotnet/roslyn/blob/main/src/Features/LanguageServer/Protocol/RoslynLanguageServer.cs). Note that Roslyn overrides `ConstructRequestExecutionQueue`, allowing it to change the override some default behavior.
+  - [`AbstractLanguageServer`](https://github.com/dotnet/roslyn/blob/main/src/LanguageServer/Protocol/RoslynLanguageServer.cs). Note that Roslyn overrides `ConstructRequestExecutionQueue`, allowing it to change the override some default behavior.
   - [`ILSPLogger`](https://github.com/dotnet/roslyn/blob/main/src/VisualStudio/Core/Def/LanguageClient/LogHubLspLogger.cs). Logs to LogHub.
-  - [`ILSPServices`](https://github.com/dotnet/roslyn/blob/main/src/Features/LanguageServer/Protocol/LspServices/LspServices.cs). Note: Roslyns `ILSPServices` implementation is a product of their specific history and needs and ends up being a combination of MEF and explicitly constructed services. We don't recommend using it to guide your creation of an `ILSPServices` implementation unless you have similarly complicated needs.
-  - [`IRequestContextFactory`](https://github.com/dotnet/roslyn/blob/main/src/Features/LanguageServer/Protocol/Handler/RequestContextFactory.cs). Provides a good example of how to get the TextDocumentIdentifier (URI) off of the `requestParam` object.
-    - [RequestContext](https://github.com/dotnet/roslyn/blob/main/src/Features/LanguageServer/Protocol/Handler/RequestContext.cs). Of particular interest here is the [retrieval of information about the document](https://github.com/dotnet/roslyn/blob/main/src/Features/LanguageServer/Protocol/Handler/RequestContext.cs#:~:text=GetLspDocumentInfoAsync) (if any). Since `RequestContext.CreateAsync` is called by `IRequestContextFactory.CreateRequestContextAsync` we maintain synchronization safety.
-  - [`IRequestHandler` or `INotificationHandler`](https://github.com/dotnet/roslyn/blob/main/src/Features/LanguageServer/Protocol/Handler/DocumentChanges/DidOpenHandler.cs). Note that this example mutates solution state and has document context.

 - [Razor](https://github.com/dotnet/razor/tree/main/src/Razor/src/Microsoft.AspNetCore.Razor.LanguageServer) has simpler requirements than Roslyn in some ways (such as `ILSPServices`) but relies on multiple other language servers (C#, HTML) for information on its contained languages.
   - [`AbstractLanguageServer`](https://github.com/dotnet/razor/blob/main/src/Razor/src/Microsoft.AspNetCore.Razor.LanguageServer/RazorLanguageServer.cs).
     - [`ConstructLspServices`](https://github.com/dotnet/razor/blob/main/src/Razor/src/Microsoft.AspNetCore.Razor.LanguageServer/RazorLanguageServer.cs#:~:text=ConstructLspServices). Razor has a simple implementation of `ILSPServices` which wraps `Microsoft.Extensions.DependencyInjection` and explicitly adds each service that it depends on.
