Full Name:
Command-Line Building

Short Name:
Command-Line Building

Type of Entity:
C#

Abstract:
You can invoke the C# compiler by typing the name of its executable file (csc.exe) on the command line. If you use the Visual Studio Command Prompt (available as a shortcut on the start menu under Visual Studio Tools), all the necessary environment variables are set for you. Otherwise, you might need to adjust your path in order to invoke csc.exe to be invoked from any subdirectory on your computer. If you do not use the Visual Studio Command Prompt, it is necessary to run vsvars32.bat to set the appropriate environment variables to support command line builds. For more information on vsvars32.bat, see How to: Build from the Command Line.
