title: Xamarin debugger won't attach due dll
body: <p>I've got a xamarin-forms pcl/android/ios) solution referencing a dll compiled from <a href="https://github.com/eclipse/paho.mqtt.m2mqtt" rel="nofollow noreferrer">M2Mqtt</a> (mono).</p>
  
  <p>The app worked fine and still does. I'm still able to compile an run the app on my device, except I can't debug anymore. As soon as the app starts, the breakpoints change from red dots to red circles.</p>
  
  <p>It all started a while ago after I installed some updates (beginning of May). At first I thought this was due to a problem with the latest Xamarin.Forms update, but even reverting to an older one didn't help. I've installed VS2017 community for mac, but no luck. Yesterday I tried to run the debugger on VS2017 on PC, also no luck. I then started to remove references, deleting packets and now I know it's this dll I compiled which is the cause of the debugger not attaching anymore.</p>
  
  <p>How ever, since the app is still working fine and since I can't do without this dll ... does anybody have an idea how I could get the debugger working again?</p>
  
  <p>Best Gerrit</p>
