CodeConverter VS VsVIM

There's also this VS extension that does a good job (more useful for converting files): https://github.com/icsharpcode/CodeConverter

If you indeed decide to migrate to C#, here is an excellent tool to help you automate the process and do much of the tedious work for you: https://github.com/icsharpcode/CodeConverter Its not perfect, but it alleviates most of the manual work.

I've migrated hundreds of thousands of VB.Net lines to C# with great help of https://github.com/icsharpcode/CodeConverter and few additiona custom scripts (for stuff they mostly fixed directly, so little need for them anymore).

I'd start with installing the VsVim extension and see how you go from there. https://github.com/VsVim/VsVim/wiki

You’re right it is emulated vim - https://github.com/VsVim/VsVim

The three main Vim emulators I've used are VsVim for Visual Studio, VSCodeVim, and IdeaVim. I've had generally good experiences with all of them, and they can all effectively emulate the main features of Vim that I find useful. As long as I can use the standard motions and keybindings and create some simple imap and nmap rules, I'm happy. If the emulator supports macros and relative line numbers that's even better.
