I have a class with a list property that seems to lose an element under certain circumstances. I cannot find out when this happens.
So what I’d like to do is set up a Visual Studio breakpoint that will pause the program the moment this value changes. A conditional breakpoint would not work in this scenario, since I have no idea what is removing this breakpoint.
To put it another way, I want my program to stop the moment myList.Count evaluates to a new number.
Any ideas on how to do this?
This is not possible in C# or any of the other .NET languages due to CLR limitations. The Visual Studio native code debugger supports data breakpoints (link) for C++ code which do exactly this but this is not supported for managed code. You could try to break on or intercept
AddandRemovemethod calls on the collection as suggested in the other answer to this question.
