When you build a Test Studio test project in Visual Studio, four dll's are added to the output folder that don't appear to serve any purpose:

1) Autofac.dll
2) Microsoft.CompilerServices.AsyncTargetingPack.Net4.dll
3) Newtonsoft.Json.dll
4) Telerik.TestStudio.Shared.dll

One customer is using a different version of Newtonsoft.Json.dll and this is creating a conflict as they are putting both the build of the application and the test project into the same drop folder.
