Potential Roslyn Analyzers

It may be beneficial to create a built-in set of Roslyn Analyzers for Xamarin.Android applications that can be used to steer users away from patterns that are less than ideal or flat-out will not work. Often times, .NET doesn't provide a better way to message these things outside of (ab)using [Obsolete] to surface warnings to users.

We often mention something would be a good candidate and then forget about it, so this page is where we can collect proposals should we create an Analyzer pack.

Potential candidates for Analyzers:

• Do Not Override Application.AttachBaseContext (Context) - Application.AttachBaseContext (Context) is used by Xamarin.Android startup, and overriding it can make the application unable to start up.
