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.
