Pulled the latest code for the ComWrappersGeneration solution from main, it doesn't build out-the-box:

  • dotnet\samples\core\interop\source-generation\ComWrappersGeneration\Server\bin\Generated\dnne-analyzers\DNNE.AttributesGenerator\DnneAttributes.g.cs(40,27,40,47): error CS0101: The namespace 'DNNE' already contains a definition for 'C99DeclCodeAttribute'
  • dotnet\samples\core\interop\source-generation\ComWrappersGeneration\Server\bin\Generated\dnne-analyzers\DNNE.AttributesGenerator\DnneAttributes.g.cs(59,27,59,43): error CS0101: The namespace 'DNNE' already contains a definition for 'C99TypeAttribute'
  • dotnet\samples\core\interop\source-generation\ComWrappersGeneration\Server\Exports.cs(19,42,19,63): error CS0121: The call is ambiguous between the following methods or properties: 'C99TypeAttribute.C99TypeAttribute(string)' and 'C99TypeAttribute.C99TypeAttribute(string)'
  • dotnet\samples\core\interop\source-generation\ComWrappersGeneration\Server\Exports.cs(19,81,19,102): error CS0121: The call is ambiguous between the following methods or properties: 'C99TypeAttribute.C99TypeAttribute(string)' and 'C99TypeAttribute.C99TypeAttribute(string)'
  • dotnet\samples\core\interop\source-generation\ComWrappersGeneration\Server\bin\Generated\dnne-analyzers\DNNE.AttributesGenerator\DnneAttributes.g.cs(65,16,65,32): error CS0111: Type 'C99TypeAttribute' already defines a member called 'C99TypeAttribute' with the same parameter types
  • dotnet\samples\core\interop\source-generation\ComWrappersGeneration\Server\bin\Generated\dnne-analyzers\DNNE.AttributesGenerator\DnneAttributes.g.cs(46,16,46,36): error CS0111: Type 'C99DeclCodeAttribute' already defines a member called 'C99DeclCodeAttribute' with the same parameter types`

FYI, if I fudge the namespace (just to get something built) then I also get the following warnings:

  • Server.g.obj : warning LNK4104: export of symbol 'DllGetClassObject' should be PRIVATE
  • Server.g.obj : warning LNK4104: export of symbol 'DllRegisterServer' should be PRIVATE
  • Server.g.obj : warning LNK4104: export of symbol 'DllUnregisterServer' should be PRIVATE

They are marked as private in server.def so this warning seems erroneous? Also, surely you wouldn't want them as private as regsvr32 would then fail to find the entry points? (as it stands regsvr32 fails anyway because it can't find them!)

Has anyone actually tried building/running this sample?!

(on the private exports point - I'd forgotten that COM finds the entry points via a different mechanism so private is actually correct)

Any thoughts, @jtschuster @AaronRobinsonMSFT?
