Can we Debug Xaml in WPF?

Question

Can we Debug Xaml in WPF? Is there any external tool or VS plugin which can do that?

Answer 1

I don't agree with others that it's not possible to debug XAML, but it's true that there are no powerful tools available for this.

As Mark says in this post - http://markegilbert.wordpress.com/2008/03/15/debugging-xaml/

So, the simple answer is yes, you can debug problems with XAML. The longer, more qualified answer is that while it’s possible, the support isn’t terribly robust yet but should improve with newer dev environments (Visual Studio, Expression Blend, etc.).

Simply add this to your project file:

true

Now we at least get line number information on the problem :)
