If you merge main, I have introduced a RawInput object - maybe you can leverage that instead of special casing this type. So instead of passing in EntityMessageEvent, the caller would pre-serialize EntityMessageEvent, construct RawInput from that, and pass into the send event method.

That might work. I will give it a try.

RawInput is marked Obsolete on purpose - just suppress the message. It is done that way to have an "I acknowledge" before using it.

Where is AsRawInput() expected to be called? By the dotnet isolated SDK shim layer?

Yes. This is the corresponding PR: microsoft/durabletask-dotnet#207

Revises how to avoid double serialization, and exposure to application-defined serialization settings, for entity message serialization. This is a challenge because orchestrators that send messages to entities have to do so by calling
SendEvent, which serializes the content using the application-defined serializer.Previously, double serialization was avoided by serializing to
JObject. But that is hacky and does not actually work with STJ.Instead we now revise the
SendEventimplementation in DurableTask.Core directly, so it can detect EntityMessageEvents and use the internally defined serialization mechanism.
