I have a List collection, where a collection of objects is a typical user object with a typed typed name, I have about 300 objects in the collection.

The best you can get is DotTrace

You can use a memory profiler like the .NET Memory Profiler . MS also has a free CLR Profiler , but I'm not sure if it shows memory allocation since I never used it.
