It can be annoying to open the IDE every time you need to build a .NET solution or project. Fortunately, .NET ships with a command-line utility called devenv.exe that you can use to build a solution or a project from a command line. To use it, open a command window and type the following command, using the appropriate path to your solution or project:
devenv /build Debug "
The preceding command builds the specified solution or project in Debug mode. If any build errors occur, devenv.exe displays them in the command window. Check out the topic Devenv Command-Line Switches for more information.
