How is the Query parameter bound in the OnGetAsync methods?

[hlaueriksson]

The Query parameter in the OnGetAsync methods, for example in Courses/Delete.cshtml.cs, is automatically bound.

Is this configured in the project, or is it something that comes out of the box from Razor Pages?

Yep! It comes out-of-the-box with Razor Pages and model binding.
