title: UWP App 'System.IO.FileNotFoundException' in mscorlib.ni.dll Exception at startup
body: <p>I have a Xamarin.Forms solution that contains a UWP project. Since my dev machine is Windows 8.1, I set up Remote Debug in another pc with Windows 10 installed in my same LAN. So, in Visual Studio I have to Right-Click to my UWP project and choose "Deploy" ensuring that "Remote Machine" is selected. After that I can Debug by hitting Remote Machine.</p>
  
  <p>It worked, the app worked with no problem using this Remote Debug.</p>
  
  <p>Since this UWP didn't have its own Assets (Logos, icons, etc) i opened the Manifest Designer to choose the images in Visual Assets section. Compiled, Deployed, and tried to remote debug again.
  Now the app doesn't open, and I get the following Exceptions:</p>
  
  <pre><code>AppConsume.UWP.exe' (CoreCLR: CoreCLR_UWP_Domain): Loaded 'C:\Users\Usuario\AppData\Local\DevelopmentFiles\f736c883-f105-4d30-a719-4bf328872f5eVS.Debug_x86.JOHN_SMITH\Xamarin.Forms.Platform.dll'. Cannot find or open the PDB file.

  <p>I tried other solutions like deleting Package Data folder described here: <a href="https://stackoverflow.com/questions/37960616/exception-thrown-system-exception-in-mscorlib-ni-dll-on-uwp-app-start">Exception thrown: &#39;System.Exception&#39; in mscorlib.ni.dll on UWP App Start</a>, with no success.</p>
  
  <p>Any Ideas?</p>
  
  <p>UPDATE:
  After checked System.IO.FileNotFoundException in Breakpoint settings I'm able to get more info about the current exception.</p>
  
  <p>In <code>Xamarin.Forms.Forms.Init(e);</code> from App.xaml.cs file is throwing this exception:</p>
  
  <pre><code>Could not load file or assembly 'ClrCompression, Culture=neutral, PublicKeyToken=null' or one of its dependencies.
  </code></pre>
  
  <p>I also updated UWP package to 5.2.2</p>
