• Using the Type Library Importer (Tlbimp.exe) provided by the .NET Framework SDK.

  Producing a primary interop assembly by using Tlbimp.exe to import a type library is straightforward. Tlbimp.exe provides the following safeguards:

  • Checks for other registered primary interop assemblies before creating new interop assemblies for any nested type library references.

  • Fails to emit the primary interop assembly if you do not specify either the container or file name to give the primary interop assembly a strong name.

  • Fails to emit a primary interop assembly if you omit references to dependent assemblies.

  • Fails to emit a primary interop assembly if you add references to dependent assemblies that are not primary interop assemblies.

• Creating primary interop assemblies manually in source code by using a language that is compliant with the Common Language Specification (CLS), such as C#. This approach is useful when a type library is unavailable.

You must have a cryptographic key pair to sign the assembly with a strong name. For details, see Creating A Key Pair.
