    .NET Assembly with COM compatibility problems

    I have . VB.NET DLL that I have made COM visible and it works fine.

    However, I've now added another class which I also want to expose to COM but I am now getting an erro when I build it:

    Error 1 The assembly {...} could not be converted to a type library. Type library exporter encountered an error while processing 'TOPSMileageLookup.JobMileage, TOPSMileageLookup'. Error: Type 'JobMileage' and type 'Job' both have the same UUID.
    JobMileage is the name of the original class I had that is COM visible and it worked fine when it was on it's own. Job is the name of the new class.

    Now, the obvious suspician is that I have copied over my COM GUID's but I can assure you that they are most certainly different. But what else could it be?

    Everything I say is either loose interpretation of dubious facts or idle speculation rooted in irrational sentiment.
