Allocations in Visual Studio Extension:

Allocation Grouping

Allocations are grouped by stack traces. A stack trace is a set of callers at the moment when the allocation is made. As several allocations can share same stack traces, it's a good idea to group them, because the same code can make hundreds of allocations.

Columns

There are columns that show different information about each allocation:

Column Name	Description
Source File	Source file name and line number of the place in the code where the allocation was made.
Value	Allocation value if it makes sense for the allocation type.Otherwise shows .
Hit Count	All allocations are grouped by stack trace.Hit Count is the total number of allocations with the same stack trace.
Leak Type	Type of the allocation. Please find the list of types in,How to find a memory leak.
Module Name	Name of the module that made the allocation.
Module Path	Full path to the module that made the allocation.
Size	Allocation size if it makes sense for the allocation type.Otherwise shows .

Select Columns

You can select which columns to show or hide by clicking the Columns button:

Stack Trace

For each allocation, you can view the stack trace of the moment when the allocation was made. Just select the allocation:

Stack Trace Form

The checkbox "Show full stack" switches between the full and the short form of the stack trace.

The short form doesn't include entries that don't have source code information:

The full form includes all entries:
