Interop Tools (.NET Framework)
The tools provided in this section simplify and reduce the amount of code required to perform interop tasks such as enabling COM clients to use .NET Framework classes that are dependent on the common language runtime.
Among other things, these tools convert and generate type libraries and produce and register classes and assemblies. They enable developers to use existing design and programming methodologies, whether types are dependent on the common language runtime or on COM.
These tools are automatically installed with Visual Studio and with the Windows SDK. The best way to run these tools is by using the Visual Studio or Windows SDK Command Prompt.
