title: Visual Studio 2015 - Adding Android Support Library v4 and v7 to use DrawerLayout and ActionBarDrawerToggle
body: <p>I am trying to add these 2 support libraries to my project through Nuget Manager in Visual Studio in order to be able to use <strong>DrawerLayout</strong> and <strong>ActionBarDrawerToggle</strong>.  However, both libraries are failing to install with the same error:</p>
  
  <p>*****Could not install package 'Xamarin.Android.Support.Compat 24.2.1'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.5', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.***** (the screenshot of the error is also provided at the bottom)</p>
