A working web service is broken after installing ServiceStack.Logging.Log4Net with package-manager (in VS Express 2012 Web)
The exception thrown on initializing is: Method 'Add' in type 'ServiceStack.ServiceHost.ServiceRoutes' from assembly 'ServiceStack, Version=3.9.4.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.
This happened after installing logging in two different applications. (I deliberately tried breaking the second one by installing logging, just to be sure, and it did break...) Cleaning and rebuilding the whole thing makes doesn't fix this.
Any help is welcome.
