Have you tried VSCode with the Rust(racer,rustfmt) + lldb integration? I've been pretty impressed with it so far. FWIW C# <-> Rust integration is really straightforward. You can actually pass delegates as C fn pointers and then treat them as a closures in Rust. Much less painful that I initially thought.

It is not yet the same as Blend + Visual Studio (C#, F#, C++/CX, C++/CLI). Yes, I do use VSCode, but only for dabbling on Rust during plane/train travels. The language is not yet at a level it just fits on MS stack and is requested by our customers on their Requests For Proposals. Regarding C# <-> Rust interoperability, it is very badly documented. I gave up on searching for it, and just used C# <-> C++/CX <-> Rust instead. Or I am very bad searching for it.

  C# <-> Rust is pretty straightforward. Just follow the C FFI side on Rust and C# has standard marshal mechanisms for calling C code. extern/dllimport[1] Covers most of it. There's automatic conversion for CString/string and delegates as function pointers. If you need to go deeper than that there's the marshal namespace[2]. Going through C++/CX sounds really painful.

    > C++/CX sounds really painful. Not for someone that knows C++ since C++ARM. :) I am pretty comfortable with C# and native interop, my issue was trying to map Rust strings with .NET UTF-16 ones, including passing ownership from Rust to .NET side.

      If I remember right you can specify encoding as an attribute on the extern decl.

  Have you seen the FFI omnibus http://jakegoulding.com/rust-ffi-omnibus/ http://jakegoulding.com/rust-ffi-omnibus/ which includes C# examples?

    No, thanks for pointing it out.
