Hi; that is protobuf-net, which has a very different API to some of the core
google libs. It supports use frmo .proto, but is also intended to work
reasonably nicely with common / existing .NET types (that /aren't/ generated
from .proto).
To that end - it indeed supports generics at runtime; this largely works
like templates. To reproduce this in .proto, you'd need a different message
(or family of messages) per "T" that you expect.
