Requirements for Registration-Free COM Interop

Support for registration-free COM interop varies slightly depending on the type of library assembly; specifically, whether the assembly is unmanaged (COM side-by-side) or managed (.NET-based). The following table shows the operating system and .NET Framework version requirements for each assembly type.

Assembly type Operating system .NET Framework version
COM side-by-side Microsoft Windows XP Not required.
.NET-based Windows XP with SP2 NET Framework version 1.1

The Windows Server 2003 family also supports registration-free COM interop for .NET-based assemblies.
