C# Language Specification

Attributes for Interoperation

Note: This section is applicable only to the Microsoft .NET implementation of C#.

1. Interoperation with COM and Win32 components

The .NET run-time provides a large number of attributes that enable C# programs to interoperate with components written using COM and Win32 DLLs. For example, the DllImport attribute can be used on a static extern method to indicate that the implementation of the method is to be found in a Win32 DLL. These attributes are found in the System.Runtime.InteropServices namespace, and detailed documentation for these attributes is found in the .NET runtime documentation.
