title: How to use M2Mqtt in Xamarin Forms targeting .Net Standard 2.0 with fallback portability?
body: <p>I am trying to integrate MQTT in a cross platform app targeting Android as well as Universal Windows Platform (UWP). However am stuck at integrating M2MQTT nuget package. </p>
  
  <p>When I try to install the above nuget package following error is shown even after installing Microsoft.NETCore.Portable.Compatibility for backward compatibility. </p>
  
  <pre><code>Package M2Mqtt 4.3.0 is not compatible with netstandard1.4 (.NETStandard,Version=v1.4). Package M2Mqtt 4.3.0 supports:
    - net39-cf (.NETFramework,Version=v3.9,Profile=CompactFramework)
    - net45 (.NETFramework,Version=v4.5)
    - netmf42 (.NETMicroFramework,Version=v4.2)
    - netmf43 (.NETMicroFramework,Version=v4.3)
    - win81 (Windows,Version=v8.1)
    - wpa81 (WindowsPhoneApp,Version=v8.1)
  Package restore failed. Rolling back package changes for 'Sample.UI'.
