The .NET Memory Profiler window contains a menu, a toolbar, a status bar, several tab pages, two dropdown lists for selecting snapshots, and optionally a selector for runtimes and AppDomains.

The menu and the toolbar provide access to all the available commands. The tab pages are used to present different views of the contents of the GC heap, both snapshot information and real-time information. Additionally, information about call stacks and native memory is presented. The available tab pages are:
•
Start

Start page provides quick access to common tasks, such as starting a profiling
session, starting guided profiling, and opening a previous session file. It will
be hidden as soon as an active session is started or a session is loaded. Use
the New session command to get back to the Start
page.
