Csc Class

Article
05/05/2015

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Implements the Csc task. Use the Csc element in your project file to create and execute this task. For usage and parameter information, see Csc Task.

MSBuild is now included in Visual Studio instead of the .NET Framework.You can use MSBuild 12.0 side-by-side with versions previously deployed with the .NET Framework.For more information, see What's New in MSBuild 12.0.
