[Performance counter] # Gen 0 Collections [Description] 
Displays the number of times the generation 0 objects (that is, the youngest, most recently allocated objects) are garbage collected since the application started. Generation 0 garbage collection occurs when the available memory in generation 0 is not sufficient to satisfy an allocation request. This counter is incremented at the end of a generation 0 garbage collection. Higher generation garbage collections include all lower generation collections. This counter is explicitly incremented when a higher generation (generation 1 or 2) garbage collection occurs. This counter displays the last observed value. The _Global_ counter value is not accurate and should be ignored.
