WCF friction

May 13, 2008

Today I spent some time (thank God no more than 15 minutes) tracking down a WCF issue from hell. Every time I made a call to the service I got the following exception:

System.ServiceModel.CommunicationException : The underlying connection was closed: The connection was closed unexpectedly.

This is really helpful, isn't it? Fortunately there is some tool that helped me out a great deal: Service Trace Viewer Tool (SvcTraceViewer.exe). Turns out that I forgot to place a DataContract attribute on one of my DTO objects.

Why am I too stupid to deduce this from the exception message in the first place?

If you're interested in an in-person or online course that teaches you and your team how to write maintainable unit tests and get the most out of TDD practices, make sure to have a look at our trainings and workshops or contact us at infonull@nullprincipal-itnull.be.
