Loading .net f/w 3.5 DataSet Extensions in SQL Reporting Services 2005
Hello, We are using DataSet Extension in Reporting Services 2005. Everything works fine when the Extension was targetting .net framework 2.0. When we moved the extension to .net framework 3.5, and have not changed any of the other configurations, I am getting following error - Any suggestions if this can be possibly done in Reporting Services 2005. If yes, any ideas to fix it. w3wp!library!9!11/14/2010-23:25:43:: Call to CreateSnapshotAction(). w3wp!extensionfactory!9!11/14/2010-23:25:45:: e ERROR: Exception caught instantiating DataSet report server extension: System.IO.FileLoadException: Could not load file or assembly 'Microsoft.ReportingServices.Interfaces, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies.

To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog]. . w3wp!processing!9!11/14/2010-23:25:45:: e ERROR: The connection object of the data source type DataSet does not implement any of the required interfaces. w3wp!library!9!11/14/2010-23:25:45:: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.DataExtensionNotFoundException: An attempt has been made to use a data extension 'DataSet' that is not registered for this report server.
