The major version number.


The minor version number.

Before exporting an assembly using TypeLibExporterFlags with the CallerResolvedReferences value, you can use this method to retrieve the type library version from the assembly.

If you do not apply the TypeLibVersionAttribute attribute to an exported assembly to explicitly control the version number of the generated type library, the type library will have the same version number as the assembly.
