No, it's a bug in IIOP.Net. omniidl is correct in not including the
"MyModule" within the repository id. See section 10.6.5.2 of the CORBA
2.6 specification:

        ...
        The specified prefix applies to RepositoryIds generated after
        the pragma until the end of the current scope is reached or
        another prefix pragma is encountered. An IDL file forms a scope
        for this purpose, so a prefix resets to the previous prefix at
        the end of the scope of an included file:
        
        ...
        
        If an included file does not contain a #pragma prefix, the
        current prefix implicitly resets to the empty prefix:
        
          // E.idl
          interface E {};
        
          // F.idl
          module M {
            #include <E.idl>
          };
        
        The repository IDs for module M and interface E in this case
        are:
        
          IDL:M:1.0
          IDL:E:1.0
        

As a work-around for the bug in IIOP.net, you can use #pragma prefix
"MyModule" at the start of myInterface.idl, which will mean that omniidl
uses the repository id that IIOP.net incorrectly thinks it should have.

Cheers,

Duncan.
