SSIS 2012 Method not found: void

Question

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?

I ran into this same issue on a computer with Visual Studio 2010 (although I'm sure VS2012 will have the same resolution). I installed Visual Studio 2015 and then started receiving this error when I tried to open an ADO NET source or an OLD DB Source in VS2010. I found that my DatatransformationServices files in the folder C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies had become corrupt. I copied all Microsoft.DatatransformationServices files from a computer where VS2010 was working to my local computer, folder C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies.

You can use a command like the following from cmd to do so:

copy /Y "\\\GoodComputerName\C$\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.DataTransformationServices.*.dll" "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\"

I then added the assemblies to my cache using the following commands in cmd (just change the directory with gacutil to your newest version in the folder C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin and change the folder for Visual Studio to the folder for the version in which you are receiving the error):

cd "C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools"
gacutil /if "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.DatatransformationServices.DataFlowUI.dll"
gacutil /if "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.DataTransformationServices.Design.DLL"
gacutil /if "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.DataTransformationServices.DTSExecUI.Controls.dll"
gacutil /if "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.DataTransformationServices.Interfaces.dll"
gacutil /if "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.DataTransformationServices.VsIntegration.DLL"
gacutil /if "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.DataTransformationServices.Wizards.DLL"
