Question

I have a class that has many child collections, which are all lazy loaded using Lazy < T >. When debugging is it possible to have those child collections display even if they are not loaded? Or to force evaluation when debugging? Here is a screenshot of the quick watch on one of the child collections. The message the debugger displays is “The function evaluation requires all threads to run.”, which makes sense to me, I just want these child collections to be more debugger friendly.

This may not be the easy way but in VisualStudio you can create your own debug visualizers for specific types. So you could create a visualizer that evaluated the Lazy to get the value and then expose the result to be visualized again.
