问题
I have a C++/CLI assembly (compiled for .NET 3.5 that comes with Windows 7).
The assembly is marked as ComVisible(true). It contains 2 classes and 1 interface. Both classes are marked as ComVisible(false) so they shouldn't matter. The interface is marked with InterfaceType(ComInterfaceType::InterfaceIsIUnknown) and a specific GUID. This interface needs to be registered.
When I try to register this assembly using RegAsm.exe AssemplyName, I get this warning:
RegAsm : warning RA0000 : No types were registered
My assembly depends on 3 other assemblies which are in the same directory as my main assembly. 2 of them register with no problems and the 3rd is not marked as ComVisible.
Any ideas why I'm unable to register my assembly?
回答1:
It looks like the assembly wasn't being registered because it didn't contain any classes available for registration, just the one interface. As soon as I added a dummy class to the assembly, the warning went away and the assembly got registered.
