I recently deployed a .Net 4 WCF Data Service hosted on IIS 6, within a corporate environment (intranet), using Entity Framework. I access the service using OData and have been successful retrieving data from tables hosted on SQL Server 2005.

The issue is that I am unable to insert new rows. What I’ve done so far is to set entity rights to ALL -> ie. 

config.SetEntitySetAccessRule("*", EntitySetRights.All);

I’m using integrated security on IIS. When I do a POST using jQuery, it returns 500 error code. I’m able to insert rows to a local database in my development environment.

Thanks

    I figured it out. I was receiving error

    “Unable to update the EntitySet because it has a DefiningQuery and no >element exists in the element to support the current >operation.”

    This was caused because the table, although having an identity field, didn’t specify it as a Primary Key. Set the Primary key and all is well.

    Fixing the System.Data.UpdateException – DefiningQuery and no Error helped.

    Thanks
