…ignalR native AOT Support streaming ValueTypes from a SignalR Hub method in both the client and the server in native AOT. In order to make this work, we need to use pure reflection to read from the streaming object. Support passing in an IAsyncEnumerable/ChannelReader of ValueType to a parameter in SignalR.Client. This works because the user code creates the concrete object, and the SignalR.Client library just needs to read from it using reflection. The only scenario that can't be supported is on the SignalR server we can't support receiving an IAsyncEnumerable/ChannelReader of ValueType. This is because there is no way for the SignalR library code to construct a concrete instance to pass into the user-defined method on native AOT. Fix dotnet#56179
