- Just deleting the servicereference and readding it doesn’t work
- Restarting VS neither
- Both of them are also no solution
And now what really helped me:
- Inside of the project folder there is a file named <ProjectName>.suo – a small hidden system-file which contains all solution information from VS. This file could be of real big size (which would slow down your intellisense) and after deletion of it the web-service will be updateable (in my case I just re-added it to the Silverlight-project)
Hope I could help someone out there with this information… I couldn’t find anything on the net about this.
