I am looking at differences between using WPF in .NET or using Silverlight 4 for the GUI front end of an app that connects to WCF services.
I have read that net.tcp binding in Silverlight 4 only supports transport level reliability. With a WPF desktop app we can use message level reliability.
What is the actual difference? If transport level reliability ensures that all TCP packets get through, doesnt that also mean that all WCF SOAP messages will also get through?
