Hi ,

The question is that I try to create an instance to a variable in a loop and don't use this variable.
Like this :

Then I use the 'Diagnostic Tool' in VS to track the memory in managed heap , however , I get only a count of Foo type in heap without GC behavior , it makes me very confuse. Hence , I infere that there is a optimization at run time for the variable which don't use in context and this optimization in order to save memory to only allocate one time in managed heap as no impact for application. I'm very very very thank you to give me some advice for that as this question let me can't keep good sleep every day.
