When I click the configuring dataset button in data source I get the following error message: "Could not load type 'Microsoft.VisualStudio.DataDesign.SyncDesign.SyncDesigner.SyncFacade.SyncManager' from assembly 'Microsoft.VisualStudio.DataDesign.SyncDesigner.DslPackage, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f711d50a3a'." Jeg bruker Visual studio 2008 Professional Edition. Before I installed Visual Studio I installed VisualBasic Express and in this application this functionality is working just fine. What can I do to be able to update my database whit the data source manager?
