Xamarin.Android and the ART of crashing

  At this time developers and power users are moving over to ART. Xamarin.Android does not yet have support for ART. Side note: Everything compiles, deploys and runs…..until it doesn’t.

Pretending to be dumb.

Reading data and displaying it on a screen. It’s most of the applications that we build. Each application has a problem area but it’s often a small part of the application.

A pattern with a name so horrible no one wants to spend the time to review what it means. </snark> http://www.objectmentor.com/resources/articles/lsp.pdf The Liskov_substitution_principle come down to two things: A base class should not have to know about the classes that derive from it.
