What's New

Previously when using Duplex contract, failure to capture synchronization context on channel factory open. The behavior now matches .NET framework, by default, we will now capture the synchronization context, and will dispatch callbacks to the captured context. To revert to 4.x behavior, apply the CallbackBehaviorAttribute with the UseSynchronizationContext property set to false.

• Fixes sync context capture and multiple async continuation issues (#5044)
• Mtom fixes (#5069)
