Type Library to Assembly Conversion Summary
This section describes how the import conversion process transforms type information as it converts a COM-style type library to .NET Framework metadata.
The .NET Framework provides both tools and an API to perform type library to assembly conversion. Although you have several mechanisms for generating an assembly from a type library, each produces the same results. For simplicity, this section describes only the Type Library Importer (Tlbimp.exe) tool in conjunction with the conversion rules for importing type information. For a description of alternative mechanisms for importing an assembly, see Importing a Type Library as an Assembly.
