Error updating service reference

问题:

When trying to update a service reference in a class library (VS2013), i get the following error.

"The configuration for the service reference could not be updated due to the following issue: An error occurred creating the configuration section handler for system.serviceModel/bindings: AssemblyResolveEvent handlers cannot return Assemblies loaded for reflection only."

This same error happens when i try to delete the reference as well.

Any help in sorting would be greatly appreciated.

I've had the same issue after updating to VS2013 Update 2.

I've solved the issue by temporarily cutting the whole system.serviceModel section out of web.config, pasting it somewhere else like Notepad. Then, I've saved the web.config without the service model section. Then, I was able to update the service reference successfully. After updating the service reference, I've pasted the service model section back to web.config and it worked successfully.

I was able to work around this similarly to Can by temporarily removing the extensions element of the system.serviceModel section and any associated extension elements. In my case the extensions were Azure Service Bus extensions.

In my experience it has been as simple as to delete the service reference and re-adding it. For example, last time it happened it was on a WebService (not WCF, the old one), and the error started appearing after we changed one of the classes that was being sent as a return from different routines/functions. After adding one more property to the class, it started going crazy and prompting errors everywhere. Just a simple Delete and re-Add Service Reference did the trick.
