Porting .net libraries in to the C++ x20

[IrakliLomidze]

Dear Herb
I Know that Is not the right place to initiate this topic, but I did not find a better way to contact you.
As you work for Microsoft, you are the best person to initiate those topics.
C++ has a smaller library than .net or java, and that why it does not attract business developers.
Now C++ has every feature (like Reflection, Metaclasses, lambdas, ….) to initiate developing libraries for business applications. What do you think to port existing .net libraries into the C++.
At least a good serialization library (json, xml, …)
ORM (EF of Hibernate), ADO.NET
Web Application Framework (Developing REST and gRPC)
It will be nice to include it in the standard library or TS or be separate and has good support from large companies such as Microsoft.

What do you think all about?
