Visual Studio is the defacto editor, but what are our other options that avoid a heavy UI while still integrating with a C# build chain?
Looking for options which preferably use vi or vim directly, and those which emulate some or all of the functionality of vi and/or vim.
Here is a guide on Vim C# compiling.
In response to the comments -
It sounds like your goal is to have a fully functional IDE that works cross platform for C# development, not necessarily to use VIM. If that's the case, you can use MonoDevelop on all platforms (including Windows, but that's a bit trickier), and since you're probably already using the mono compilers on your other platforms, this might be a nicer option.
I'm not connected with the company in any way, but I've heard very good things about ViEmu. If the price were a little lower, I'd get it myself, because I love the editing power of Vim.
MSBuild is a very powerful analog to Ant.
Use msbuild project files to manage your .NET projects, and write a nmake file that calls msbuild.
Map your vi make command to nmake
You can just use :make to do a build
If you are on the latest versions of VS, then the solution files can be built with MSBuild, which is basically a NAnt equivalent.
Otherwise, call csc to compile the files yourself.
I use nant as a build file (very simple and flexible) then call :set makerpg=nant\ compile.all
Then whenever you wan't to compile just type :mak
This can be extended with custom error formats etc.
