   The error "Initialization failed:: Could not load file or assembly Microsoft.Xrm.Tooling.Connector" comes up on browsing on Sitefinity site.
   
   Earlier our Sitefinity site was working fine, after adding the dlls of tpc into bin folder, we open Sitefinity site then install the Crm portal connector modules. After this installation, the site doesn't work and throwing the "Initialization failed : Could not load file or assembly Microsoft.Xrm.Tooling.Connector" error.
   
   The Same error is thrown when we open the site from visual studio.
   
   Sitefinity Version : 10.1.6502.0
   TPC version : 4.2.10165.0133
   CRM version : Crm 2011
   
   What could be the cause of this issue?

   Check in your project’s \bin folder and look at the version for that .dll file. We’ve seen situations where NuGet puts in version 2.2.0.0 into your \bin folder, but TPC is expecting 2.1.0.0. You may have to copy the contents of the TPC .zip file back into your \bin folder and try again.
