How to register DLL .net

Question

Hi, I studied the "Building a Class Library Component and consumet Client Application with VB.NET. This tutorial is awesome by its clarity but doesn't explain how to register the DLL. I tried regsrv32 but keep getting an error message : C:\winnt\ProfClac01.dll was loaded, but the DllRegisterServer entry point was not found. DllRegisterServer may not be exported, or a corrupt version of c:\winnt\ProfClac01.dll may be in memory. Consider using PView to detect it and remove it. Pretty long error message ! Can anyone help me out ? Used to be so easy to register DLL what am I missing in this .NET version ? Thank you, Christian
