This is pretty common, and the advantages of Rust won't overcome people being inherently lazy (not in a bad way... lazy in this sense is really more efficient).
People love C# for that very reason, once they get used to Visual Studio, convincing them to switch to something with very limited IDE support is a tough argument. Most people have better things to do with their life. Rust will get there though, just give them time.
I write C# at work using VS, and am working on getting omnisharp running so I can use VIM here instead. I have fully converted from being an IDE person to a VIMMER. So many helpful things, and keyboard binds that I can't believe I ever lived without. VsVim just isn't the same, and cannot be used in VS2008 which we unfortunately use most of the time.
