Not the author but I also moved from C# to Rust. In the first place I did not consider Rust for C# works like REST API but after I proficient with Rust I no longer want to work with C# for the following reasons:

1. Microsoft don't want to open source .NET Core debugger. 2. I tired of keeping upgrade .NET on my projects. 3. Result type in Rust make me more productive than exception in .NET. 4. async/await in Rust is lightweight and a better than .NET. 5. Thread-safety in Rust is a compiler error instead of figure out by checking the docs if type is thread-safe. 6. Community libraries in Rust has a great quality and docs.

This was purely a hobby project I wanted to test the limits of Claude and see how quickly it could do such a change. It was surprisingly very stable I still found bugs but was able to resolve them within a small time window. For additional context I didnt use Fable as only Opus was available to me.
