How do I convert a .tlb file to headers and implementation files?

I'm trying to convert mscorlib.tlb. It normally used in C++ like this:

#import "mscorlib.tlb" raw_interfaces_only              \
     high_property_prefixes("_get","_put","_putref")        \
     rename("ReportEvent", "InteropServices_ReportEvent")

How can I convert it to headers and implementation files?

I was able to use Visual Studio to compile a dummy cpp file that contained the lines above, and it produced a .tlh file. Shouldn't there also be implementation files?
