Good afternoon,  
  
I’m having some trouble using the “Team Foundation Query Work Items” action. In summary, the WorkItemTracking dll in the Visual Studio&nbsp;v2.0 folder is a .NET 4.0 assembly. Has anyone come across this? I found something similar (about an FB installer issue), but that was to do with versioning of the dll in the config files. More details below.  
  
FB IDE Version: 7.0.0.3291  
Visual Studio 2013 Ultimate  
Windows Server 2012 R2 Standard  
  
The error I’m getting in FB is as follows:  
Could not load file or assembly ‘Microsoft.TeamFoundation.WorkItemTracking.Client, Version=12.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies. This assembly is built by a **runtime newer than the currently loaded runtime** and cannot be loaded.  
  
I have checked, and the ‘Microsoft.TeamFoundation.WorkItemTracking.Client.dll’ file exists in C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\<strong\>v2.0.&nbsp;I deposited it in the FinalBuilder 7 folder, because Fusion suggested it wasn’t being picked up in the GAC,&nbsp;however ILDASM says the dll is a .NET 4.0.30319.   
  
I tried to attach the below as an attachment, but it wouldn’t let me:

Hi Nadaav   
  
 In the FinalBuilder Options, under FinalBuilder, .NET Framework version, make sure v4.0 is selected and then restart. That is the version of the CLR that FinalBuilder hosts, I suspect it’s set to v2.0 at the moment (the default in FB8 will be 4.0).

Thanks Vincent,   
  
 That’s great. I had this set to v3.5, because (due to my lack of understanding), all our .NET projects are v3.5, and I wasn’t sure how it all interacted. I thought maybe I can find an older version of the work item tracking dll, but it’s all working after your suggestion.   
  
 Thanks again, and I hope you’re well.   
  
 Nadaav.
