I have an endpoint that connects to SQL and returns a result set to the client. The WCF Service sets the MaxReceivedMessageSize to a low value and therefore the endpoint does not return a result set.

I fixed the issue by increasing the MaxReceivedMessageSize value. However, I need to see just how much data is coming from the endpoint to the client.

I tried using Postman but that's not working. What's the best way to capture what the endpoint is returning to the client?

Thank you

You can inspect or modify the incoming or outgoing messages across a WCF client by implementing a System.ServiceModel.Dispatcher.IClientMessageInspector and inserting it into the client runtime.

Inspect messages not only implements the inspector on the client side, but also manipulates the endpoint behavior.
