I tried your example but it did not work until I used "/codebase" like this:

C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\regasm
C:\work\learn\ClassLibrary1\ClassLibrary1\bin\Debug\ClassLibrary1.dll
/tlb:C:\work\learn\CallDotNetDLL\ClassLibrary1Lib.tlb /codebase
file:///C:\work\learn\ClassLibrary1\ClassLibrary1\bin\Debug\ClassLibrary1.dll

C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\regasm
C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\mscorlib.dll
/tlb:C:\work\learn\CallDotNetDLL\mscorlib.tlb /codebase
file:///C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\mscorlib.dll
