Unable to load DLL 'Microsoft.WITDataStore32.dll' (TeamFoundation.WorkItemTracking) Visual Studio 2017

Question

I have VS 2017 enterprise and I use VSTS.OS - Windows Server 2012 R2 Microsoft.WITDataStore32.dll is a native dll so we can not add it as a reference

Problem :

When I am trying to run coded UI test in my VS 2017 enterprise I get the error message "Unable to load DLL 'Microsoft.WITDataStore32.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)" at

iTestManagementService.GetTeamProject("Project Name")

Stack Trace for this is

I had already installed Microsoft.TeamFoundationServer.ExtendedClient -Version 15.112.1 nuget package. And it has the dll present in it but somehow it is not able to load it.

I also installed TeamExplorer as someone suggested but no luck

Below are the paths where Microsoft.WITDataStore32.dll and Microsoft.WITDataStore64 dlls are present in my machine

Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer
Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE
packages\Microsoft.TeamFoundationServer.ExtendedClient.15.112.1\lib\native\x86

This Question is already present here and here but its answers did not fix my issues.

Can anyone please help?

Is `Microsoft.WITDataStore64.dll` stored in `packages\Microsoft.TeamFoundationServer.ExtendedClient.15.112.1\lib\native\amd64`? Do you try to reboot your machine? — Cece Dong - MSFT, Jun 01 '18 at 07:33
yes the 64 dll is present and also I did tried with reboot as well — Pankaj Devrani, Jun 01 '18 at 07:34
Just a test, if you manually add Microsoft.WITDataStore32.dll to system32 folder, will it work? — Cece Dong - MSFT, Jun 01 '18 at 09:10
@CeceDong-MSFT No it won't work as it is a native dll. And when I try to add it it gives me error message that "Please make sure the file is accessible, and that it is a valid assembly or COM component" — Pankaj Devrani, Jun 01 '18 at 09:49
I couldn't reproduce your issue on my side. I'm using VS 15.5.2, do you use the same version? — Cece Dong - MSFT, Jun 05 '18 at 09:26
@CeceDong-MSFT I have VS Enterprise 2017 version 15.7.1 have you installed nuget package also which I have installed? — Pankaj Devrani, Jun 05 '18 at 09:38
Yes, I installed `Microsoft.TeamFoundationServer.ExtendedClient 15.112.1`, but I didn't get any error at `iTestManagementService`. — Cece Dong - MSFT, Jun 05 '18 at 09:46
@CeceDong-MSFT I also have this issue in VS 2017 Enterprise 15.5.6 with the nuget package 15.112.1 — Reed, Jul 09 '18 at 14:33
@CeceDong-MSFT did you able to connect to the team project and also did you get any error at this line of code? iTestManagementService.GetTeamProject("Project Name") — Pankaj Devrani, Jul 10 '18 at 05:14
