WCF DataServices Astoria Version 2 not returning results when called from Code
I have WCF DataService which works great when queried via directly through the browser. However, when run from Visual Studio 2010 where I'm trying to query and bind to a grid, it throws a DataServiceQueryException telling me "Resource Not Found" a 404 error. This is reall开发者_Go百科y bizarre. Any thoughts?
Are you self hosting the service? When you test the service are you running it in the VS dev server?
My though is that the service may not actually be running when you try to add service reference.
This is still having issues. The service is hosted in the client. Here is the full error:
