Hi Boris,

I wonder if there are legal experts in these newsgroups... Anyway, the best
approach from the legal standpoint IMO would be to consult your corporate
lawyer regarding the rights you have according to the 3rd party COM
component's license agreement.

I personally never heard of such restrictions in a license agreement - why
would the vendor limit the use of its product in managed code given the
popularity of .NET? What I have seen, however, is the requirement to use
software on Windows only or not to use it in an open-source project.

It would be nice if you could link to the training material suggesting that
you can't use interop libraries for 3rd party COM objects. Aren't they
saying you cannot declare these interop DLLs as *PRIMARY* interop
assemblies - this is true indeed as only the original vendor can ship PIAs.
Also, if the PIAs are available, you might be required to use them instead
of creating your own interop DLLs.
