.NET Dynamic Compile and Debug

A .NET 8 demo that compiles and executes C# code at runtime with full debugging support.

Features

• Runtime Compilation: Compiles C# functions from JSON definitions using Roslyn
• Debug Support: Enables breakpoints in dynamically compiled code via Debugger.Break()
• Version Management: Automatically recompiles when function versions change
• Hot Reload: Reload function definitions without restarting the app

How It Works

1. Functions are defined in functions.json with name, version, and source code (simulating a functions repository)
2. On execution, the app compiles the source to a DLL in the generated/ folder
3. The assembly is loaded and the Run method is invoked
4. If the version changes, the function is recompiled automatically

Usage

Start the debugger in VSCode

Or run directly, but without the debugger attached.

dotnet build
dotnet run

Select a function from the list to execute it.
