title: Microsoft Visual Studio: System.IO.FileNotFoundException in Console App that references Library that should have the File in question
body: <p>I created a c# Library class (called IfcManagerLib) in Visual Studio and installed some packages (only on the library) via the NuGet Packages Manager. Now I want to use this library through a Console App (called IfcManagerConsole), so I created one in the same solution, added a reference to IfcManagerLib and added "using IfcManagerLib;" on the top of the console class.
  However, if I start the console it always breaks at the moment it tries to execute something from the library class. It outputs the following error:</p>

  <p>(Sorry, some of it is in German, but I think you mostly know what it is supposed to say)</p>
  
  <p>What really bothers me, is that the path to the IfcManagerLib (C:\Users\David\Dropbox\Visual
  Studio\source\repos\IfcFileManager\IfcFileManagerLib\IfcManager.cs) in the above error message is not correct. It is an old path. I rebuilt the solution, unistalled and reinstalled all packages, but the error still exists. Also: "Microsoft.Extensions.Logging.Abstractions, Version=2.1.1.0" is not correct, I updated it to 2.2.0.0.</p>
  
  <p>Am I correct in the asumption that the console project does NOT need to have the packages installed that the library uses? If yes, what did I do wrong?</p>
  
  <p>EDIT: Okay. Cleaning and rebuilding the solution did a lot already. However, there is one dll called Xbim Geometry that the Console still cannot find. Here is the error message:</p>

  <p>What I find odd is that unlike the other dlls that I installed on the library project through NuGet manager, the XbimGeometry dll is located in two folders named x64 and x86 where there is a 64-bit and a 32-bit version. Could that be the problem?</p>
