If you want to code in C# using Sublime Text, then this post is for you. After this post you will be able to use Ctrl+B to build a .cs file and Ctrl+Shift+B to run the exe through the terminal.

The Steps

  1. Find the C-Sharp Compiler on your system. Normally it's in C:\Windows\Microsoft.NET\Framework\ folder. For me it is C:\Windows\Microsoft.NET\Framework\v3.5\csc.exe
  2. Add csc.exe's path to Environment Variables. The name of the variable should be csc.exe . The screenshot should assist you. csc.exe-setting
  3. Then add the csc.exe's directory to path variable. For me the directory is C:\Windows\Microsoft.NET\Framework\v3.5. Just append the directory in PATH with a preceding semi-colon (;).
  4. The create this build file for Sublime Text. Name it something like C#.sublime-build and store it in Data\Packages\User directory.
{
  "selector"  : "source.cs",
  "cmd"       : "gmcs $file_name",
  "shell"     : true,

  "osx" : {
    "path" : "/usr/local/bin:$PATH"
  },
  "windows" : {
    "cmd"  : "csc.exe $file_name"
  },

  "variants"  : [
    {
      "cmd"   : "mono $file_base_name.exe",
      "name"  : "Run",
      "shell" : true,

      "windows" : {
        "cmd": ["start", "cmd", "/k", "${file_path}/${file_base_name}.exe"]
      }
    }
  ]
}

Disclaimer - I took the base of .sublime-build from this repo. I submitted a pull request too with the enhancements.

Hope this helps !
