You have to:

  • make sure the classes that you want to use in your VB app are ComVisible
  • make sure the classes that you want to use in your VB app have a Guid assigned to it
  • it is best practice to create an interface for those classes
  • create a tlb file from the assembly using regasm
  • The .NET framework (runtime) needs to be installed. It is not that regasm will 'compile' your assembly into another language or something that does not need the .NET runtime. A runtime callable wrapper is created, so that you can invoke the .NET assembly as from VB6, which means the .NET runtime is still required.

In VB.Net you can use it normally. In previous version use Runtime Callable Wrapper. More information is here in this KB article.
