eXtreme Go Horse (XGH) Process

Übersetzung ursprünglich von https://gist.github.com/Neffez/f8d907ba8289f14e23f3855011fa4e2f

1. Ich denke, also ist es nicht XGH.
In XGH wird nicht gedacht, es wird das erste gemacht, was in den Sinn kommt. Es gibt auch keine zweite Option, die erste ist schneller.

2. Es gibt 3 Wege ein Problem zu lösen: den richtigen Weg, den falschen Weg und den XGH Weg, welcher exakt wie der falsche ist, aber schneller.

Approaching a Xamarin.Android Bindings Case

1. Investigation

One of the best ways to investigate a problematic Xamarin.Android Binding is to first ensure you have the proper tooling available:

• Diagnostic MSBuild Output Enabled(Instructions)
• Java Decompiler(http://jd.benow.ca/)
• .NET Decompiler(https://www.jetbrains.com/decompiler/)
• Binding SDK Documentation
