I wrote an article for the August 2015 edition of Windows Developer Magazin that introduces the new debugging features in Visual Studio 2015. I has recently been published online for everybody to read. If you are interested in debugging in VS2015, go check it out (note: it is written in German):

The article presents the changes in VS2015 related to debugging:

• The Exception Settings Debug Window
• Lambda Expression Debugging in the Watch Window
• PerfTips
• The Diagnostic Tools Window
• Live Visual Tree
• Live Property Explorer

As a conclusion, the article compares the following 3rd party WFP troubleshooting tools:

• Snoop
• WPF Inspector
• XAML Spy
• WinRT XAML Toolkit VisualTreeDebugger
