I have an assembly which is referencing couple of other assemblies. Everything was working fine and then I went ahead and strongly signed all of the assemblies. The assembly contains entity designer and generated entities and context objects. Now any change made in the designer results in error and I can't get rid of it. The errors are listed below. Any help would be much appreciated.
