Actually, if that is the case, if you have a .NET 1.1 application and
developed some sort of plugin architecture, and someone made a .NET
2.0-based plugin, wouldn't that cause the same problem? If so, that
really puts a damper on what type of applications can be written in .NET
(not just shell extensions - although an application crash isn't as bad
as an explorer.exe crash).

Also, you can make DLLs with .NET. A DLL is just a special type of
executable typically containing exported function names. Shell
extensions and other COM objects are usually DLLs. So, DLL Hell and
.NET Hell are now possible from within the same file. Nifty.
