Roslyn Extension FAQs

Question 1

What are the prerequisites for using the Roslyn MCP Extension?

Accepted Answer

To use this extension, you need Visual Studio 2022 or 2026 installed, along with the .NET 10.0 SDK which is required for the underlying server process.

Question 2

What C# code analysis capabilities does it offer?

Accepted Answer

It provides live diagnostics (errors, warnings), semantic find-all-references, go-to-definition, the ability to list all symbols in a file, search symbols across the solution, and retrieve detailed type information including base types and interfaces.

Question 3

What is the Roslyn MCP Extension?

Accepted Answer

The Roslyn MCP Extension is a Visual Studio extension that provides real-time semantic C# code analysis and diagnostics directly from your VS Roslyn workspace, making it accessible via the Model Context Protocol (MCP).

Question 4

How does this extension differ from other Roslyn MCP servers?

Accepted Answer

Unlike standalone servers, this extension utilizes Visual Studio's live `VisualStudioWorkspace`. This grants access to unsaved changes, real-time diagnostics, semantic find-all-references, and the full compilation state VS already maintains, ensuring accuracy and currency.

Question 5

Can it integrate with AI coding assistants or other MCP clients?

Accepted Answer

Yes, it exposes its rich semantic data via the Model Context Protocol (MCP) over HTTP/SSE. This allows integration with any MCP-compatible client, including tools like VS Code (for GitHub Copilot) and Claude Desktop, by simply configuring the server URL.
