# Introducing Custom Agents for .NET Developers: C# Expert & WinForms Expert

**[ASP.NET Blog](https://daily.dev/sources/aspnet)** · 3 min read · 70 upvotes · 2 comments

## Summary

Microsoft released two experimental custom agents for GitHub Copilot targeting .NET developers: C# Expert and WinForms Expert. C# Expert provides guidance on modern C# best practices, code integrity, and testing workflows. WinForms Expert specializes in UI design patterns, event-driven programming, and protects designer.cs files from corruption. Both agents can be downloaded from the awesome-copilot repository and integrated into projects via the .github/agents folder, with support across Copilot Coding Agent, VS Code Insiders, and upcoming Visual Studio 2022 v17.14.21.
