A snin miljun ilu, I helped developed a web service that was invoked via a custom action for a SharePoint Designer workflow. Din il-ġimgħa, il-klijent riedu li jitmexxa għall-produzzjoni (finalment!) hekk għamilna.

L-azzjoni custom maħduma multa, iżda s-servizz web hija qajmet ma, tagħtina dan l-iżball:

System.InvalidOperationException: This operation can be performed only on a computer that is joined to a server farm by users who have permissions in SQL Server to read from the configuration database. To connect this server to the server farm, use the SharePoint Products and Technologies Configuration Wizard, located on the Start menu in Administrative Tools.
at Microsoft.SharePoint.Administration.SPWebApplication.Lookup(Uri requestUri)

Turns out that I forgot to add the service to the SharePoint application pool in IIS. Once I did that, maħduma multa.

This MSDN forum posting gave me the clue I needed: http://social.msdn.microsoft.com/Forums/en-US/sharepointdevelopment/thread/2c97c004-7118-4e06-a62c-b2b0ac07ac99
