.NET for Android warning XA0105
The .NET for Android build will emit a XA0105 warning if it detects that one
of the referenced libraries or projects is using a $(TargetFrameworkVersion)
higher than the project being built. Using libraries which are targeting a
higher $(TargetFrameworkVersion)
can cause unexpected results at runtime,
especially when running on older devices.
The fix is to increase the $(TargetFrameworkVersion)
for your project to
be equal to or higher than the referenced library projects.
