Can we Debug Xaml in WPF?

Can we Debug Xaml in WPF? Is there any external tool or VS plugin whi开发者_开发问答ch can do that?

I've occassionally found these tricks here useful...

...particularly the second one where you use a dummy value converter to break in to the debugger. It's useful for seeing exactly what objects are being bound, etc.

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.).

Wayback Link | Get line numbers of XAML issues (Peter Himschoot):

Simply add this to your project file:

<!-- under the <PropertyGroup> tag -->
<XamlDebuggingInformation>true</XamlDebuggingInformation>

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

Just use google/StackOverflow to know how to debug specific XAML issues.

XAML is a declarative language and not imperative so I don't see how debugging it could be possible.

No it is not possible.
