  <p>I tried reinstalling them with nuget, but it didnt work out. I cleaned the solution and rebuild it and deleted the nuget cache. Since none of this worked, I try to add a reference per hand to the path of the dlls I found, but it seems like all of them have the version 0.0.0.0, which doesnt feel correct, but Im not sure about this.</p>
