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.
