Indeed, it is the next COM major improvement.

Basically .NET metadata replaces COM type libraries (TLB), and in 
the process COM ABI was extended to support basically anything 
from Common Language Subset (CLS) from .NET (as in types).

So UWP also supports enumerations and generics for example.

Initially the support for projections was built into .NET, Chakra 
and VC++ toolings, while everyone else was left wondering how to 
make them.

Now with that whole Project Reunion reboot of the stack, that 
infrastructure is available for others.
