I'm sorry to tell you, friend, that your article does this too. You don't explain what XAML is, for instance. Certain sentences almost read like the satire you posted: "how to do in C# code the things which are currently done in XAML (such as binding)". You also tell the reader to "edit the relevant line" which doesn't help a total beginner.
The fact of the matter is that writing for the lowest common denominator takes an incredible amount of time and writing skill. Most of us don't have one, some don't have both.
If you keep practicing technical writing, I'm sure you'll get there eventually. Just keep in mind that most people do not want to be technical writers
