In our .NET Standard solution I temporarily removed the functionality in IncomingMessageAcceptor as we were using overloads of the Socket class that are not available in .NET Standard. See 30b7a44 for the commit where this was excluded.

We need to update the code to use supported overloads. For stuff like accepting a new connection or listening (stuff that it's not in the hot path), it is fine to use the overload that returns a Task. Nevertheless for the receive operation we need to be performance conscious. We can potentially use a similar approach as in 02753a3 for that particular operation.

In order to open the solution that compiles using .NET Standard (and hence easy to check whether certain overloads are available), check out this readme
