I want to know which Mono version my project uses. How can I check it? In my project I have Mono.Android DLL. I have right clicked on it and review property. It says Runtime Version: 4.0.3. If I go to location of that DLL, I am getting this location: C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\ReferenceAssemblies\Microsoft\Framework\MonoAndroid\v6.0\Mono.Android.dll

    As you can see in the note, the Runtime Version means the version of .Net runtime this assembly was compiled against. Not the Mono.Android version.

    The version of Mono.Android.dll is related to the Android version. You could consider your Mono.Android version is 6.0.
    If you change your Target Framework version, the Mono.Android will also be changed.
