I recently got this error in every SSIS package (using Visual Studio 2012), when I want to open a OLE DB source component:
===================================
Method not found: 'Void Microsoft.DataTransformationServices.DataFlowUI.DataFlowConnectionPage.set_DataPreviewTimeout(Int32)'. (Microsoft Visual Studio)
------------------------------
Program Location:
at Microsoft.DataTransformationServices.DataFlowUI.OleDbSourceUI.SetConnectionPageDescriptions(DataFlowConnectionPage connectionPage)
at Microsoft.DataTransformationServices.DataFlowUI.DataFlowAdapterUI.AddCommonConnectionPage(DataFlowComponentForm form, String helpKeyword)
at Microsoft.DataTransformationServices.DataFlowUI.OleDbSourceUI.AddPagesToForm(DataFlowComponentForm form)
at Microsoft.DataTransformationServices.DataFlowUI.DataFlowComponentUI.EditImpl(IWin32Window parentControl)
at Microsoft.DataTransformationServices.DataFlowUI.DataFlowComponentUI.Edit(IWin32Window parentWindow, Variables variables, Connections connections)
It worked fine last week and I don't think I changed anything since then. Any suggestions?
