If you have implemented Scrum for Team System v2.2 in a TFS 2008 environment with SQL Server 2008 as the database, then you will find that you get the below error when viewing the Team Project portal
“Client found response content type of '', but expected 'text/xml'. The request failed with an empty response.No Reports”.
This occurs because SQL Server 2008 has a different web service URL to SQL Server 2005 and the component that lives on the WSS/MOSS server formulates the wrong URL.
I’ve attached a fixed assembly that will work with both SQL Server 2005 and 2008, this needs to be dropped into the GAC of the server running WSS or MOSS with Scrum for Team System. Future versions will likely not take this dependency on the TFS server.
