Question

For a view, there are corresponding .xaml and a .xaml.cs files. How are these files related?

I\'m super new to xaml - I think I see dynamic placeholders in the .xaml fil

Answer 1

The XAML file (.xaml) and the corresponding code-behind file (.xaml.cs) are two partial definitions of the same class.

Partial Classes and Methods (C# Programming Guide): https://msdn.microsoft.com/en-us/library/wa80x488.aspx

The InitializeComponent() method that is called in the constructor of the code-behind class at runtime locates a URI to the compiled XAML file and passes it to a LoadComponent() method that parses the BAML, i.e. the compiled XAML, and creates instances of the elements that you have defined in your XAML markup.

What does InitializeComponent() do, and how does it work in WPF?
