Honestly, I wish it would do less, but a lot better. Rather than adding new features, I would love to see the following addressed:
- 64-bit by default. I am developing for Windows 10, make the entire C# toolchain emit 64-bit binaries. Make devenv.exe 64-bit, make the default build/compile 64-bit
- Make the XAML editor work without bombing out in not-that-unreasonable scenarios.
- Make it faster. Everywhere. Make project startup faster, make static analysis faster, make the compiler faster.
I don't use probably 90% of what it does. You're never going to convince me VS is a better tool for deployments, managing databases, or the approximately 50 other things it tries to do, better than purpose-built, scriptable tools. Just make a fast, purpose-built code editor with good static analysis capabilities, and get out of my way. FWIW, I'm really liking Visual Studio Code these days, it's more in line with what I want.
