What is Roslyn Code Lens?

A Roslyn-based MCP server that gives AI agents deep semantic understanding of .NET codebases — type hierarchies, call graphs, DI registrations, diagnostics, and more. It is built for AI-assisted development tools working with .NET solutions.

How to use Roslyn Code Lens?

Install as a .NET global tool with dotnet tool install -g RoslynCodeLens.Mcp, or use via dnx in VS Code/Visual Studio. The server auto-discovers .sln files by walking up from the current directory, or you can pass a solution path directly, e.g., roslyn-codelens-mcp /path/to/MySolution.sln.

Key features of Roslyn Code Lens

Semantic type hierarchy and inheritance analysis
Cross-referencing call sites and symbol references
Dependency injection registration scanning
Compiler diagnostics and code fix suggestions
Dead code detection and complexity metrics
Source generator output inspection

Use cases of Roslyn Code Lens

Analyze type hierarchies and inheritance relationships in a solution
Detect dead code and unused symbols across projects
Review compiler diagnostics and apply available code fixes
Inspect dependency injection registrations and service lifetimes
Identify circular dependencies in project or namespace graphs

常见问题

What are the runtime requirements?

.NET 10 SDK and a .NET solution with compilable projects are required.

How does the server discover my solution?

It automatically walks up from the current directory to find `.sln` files, or you can pass the solution path as a command-line argument.

Does it support hot reload?

Yes. The server watches `.cs`, `.csproj`, `.props`, and `.targets` files. Affected projects are lazily re-compiled on the next tool query.

What performance can I expect?

Most queries complete in microseconds to low milliseconds after a one-time solution load of about 928 ms (benchmarked on an i9-12900HK with .NET 10.0.3).

How do I install Roslyn Code Lens?

You can install it as a .NET global tool, use the `dnx` command in VS Code/Visual Studio, or run `claude install gh:MarcelRoozekrans/roslyn-codelens-mcp` for Claude Code.
