| NAnt  Help  Task Reference  <csc> | v0.85 | 
Compiles C# programs.
      Note:  In order to have <csc> task generate manifest resource names that match those generated by Microsoft Visual Studio.NET, the value of the prefix attribute of the <resources> element should match the "Default Namespace" of the C# project, and the value of the dynamicprefix attribute should be set to "true".
