AI-Powered Roslyn Diagnostics for C#

AI-Powered Roslyn Diagnostics for C# enhances static analysis in Visual Studio by combining Roslyn’s diagnostics with AI-generated explanations from ChatGPT. It simplifies complex compiler messages and offers deeper, source-aware insights to help developers understand issues more clearly.

🔧 Installation

To install and use this extension successfully, ensure that the correct Visual Studio components are present.

✅ Required Workload

You must have the “.NET Desktop Development” workload installed.

🧠 This workload typically includes all required components, such as:

• Visual Studio Core Editor
• .NET Framework 4.7.2 Targeting Pack
• Roslyn Compiler Support (displayed as C# and Visual Basic Roslyn Compilers in the installer)

🔍 How to Check

1. Open the Visual Studio Installer.
2. Click “Modify” on your current installation.
3. Under Workloads, ensure “.NET Desktop Development” is checked.
4. Under Individual Components, verify the following (they should already be selected):
   • ✅ Visual Studio core editor

💡 If any of these are missing, the vsix installer will not allow you install the extension. Therefore, ensure the above workload and individual components are installed, then try again.

Once ready, install the extension via a .vsix file or the Visual Studio Marketplace.
