Debugging Property Settings in Visual Studio 2008 with INotifyPropertyChanged

Question

I have a class with a property that gets set by another class. Inside this property setter the program blows up.

I just need to know what class actually set the property.

I thought I could just look at the stacktrace, but because I am using INotifyPropertyChanged I think it doesn't give me the full information I am looking for.

Here is the stack trace if this helps:

    MyProject!MyProject.MyClass.MyProperty.set(string value = "") Line 24 C#

Answer 1

Hmm. . .

You can break point in your property setter and use Call Stack window to trace which one called it.

Answer 2

It's a little old school, but have you tried adding Debug.WriteLine() statements to trace your program execution? You can view the results of Debug.WriteLine() in the VS Output window while your program runs.
