CLR Compliant

From NFBSP

A CLR (Common Language Runtime) Compliant binary (Dynamically Linked Library or Executable) may be loaded as a reference into Visual Studio .NET of an equal or greater version. By doing this, you can access and use all public properties and methods in binary; however, you cannot edit anything in the binary. If you discover a bug, it is recommended to notify the original author of the binary to have it resolved. CLR compliance is provided by the original author to enable other developers to develop their own front end for the application.
