Heap Snapshot Views

Includes a list of all the types and resources in the profiled process. This list is collected during a heap snapshot and presents the number of instances and allocated bytes of each type, as well as the number of allocations performed per second.

If unmanaged resource tracking is enabled, then information about unmanaged resources is also presented in this view.

Below the Types/resources list there is a Filters list. It includes information based on saved "instance and allocation" filters. The information presented is the same as, or a subset of, the types information.

The change of live instances between two snapshots is also shown. This information can be used to find memory leaks.

By selecting to show dispose information, information about disposed and undisposed instances is presented. Undisposed instance are disposable instances that have been garbage collected without being properly disposed.

A summary of all memory usage issues that have been identified by the automatic memory analyser is also presented in this view.

The instance details also includes an instance graph, providing a visual overview of the selected instance, and all its related instances and roots.

If instance data has been collected, the values of the fields will also be displayed.

The instance fields can be presented in a style mimicking the watch windows in Visual Studio, or they can be presented in a flat style; in the order they are defined.

All root paths are listed starting with the shortest path.

The root paths are extremely useful to find out why an instance is not garbage collected.

When a reference to an instance is presented, both the instance number and the name of the referring field is included. This makes is easier to find out how an instance is referenced and why it has not been garbage collected.

The details of an unmanaged resource instances include base information such as the identifier, size and the state of the instance. Additionally, information about managed type instances that wrap the resource instance is displayed, as well as the allocation stack of the instance.

If several resource instances are created during the same function call, they will be presented as related resource instances.

In addition to the call stack of the instance creation, the function arguments provided to the creation function are also presented.

The navigation buttons can be used to easily browse through a selected set of instances.

The Native Memory Page presents information about the native memory of a process. Native memory is the memory managed by the operating system, rather than the Common Language Runtime.

.NET Memory Profiler also makes use of the information collected by the unmanaged resources tracker (if enabled) when presenting native memory, allowing more detailed information to be identified.
