The rows of Memory Usage summary table lists the snapshots that you have taken during the debugging session and provides links to more detailed views. Press F5 to run the app to your second breakpoint.Īt this point, you can begin to analyze the data. While the debugger is paused at the first breakpoint, choose Take snapshot on the Memory Usage summary toolbar. Run the scenario that will cause your first breakpoint to be hit. To create a baseline for memory comparisons, consider taking a snapshot at the start of your debugging session. (It may help to set a breakpoint here as well.) To take a snapshot at the start of your debugging session, choose Take snapshot on the Memory Usage summary toolbar. Stop (Shortcut key: Shift+ F5) and restart debugging. When the Diagnostic Tools window appears, choose the Memory Usage tab, and then choose Heap Profiling. To enable snapshots in native or mixed-mode apps, start a debugging session (Shortcut key: F5). When the app finishes loading, the Summary view of the Diagnostics Tools appears.īecause collecting memory data can affect the debugging performance of your native or mixed-mode apps, memory snapshots are disabled by default.

Set a second breakpoint at the end of the function or region of code that you want to analyze (or after a suspected memory issue occurs). If you have an area where you suspect a memory issue, set the first breakpoint before the memory issue occurs.īecause it can be challenging to capture the memory profile of an operation that interests you when your app frequently allocates and de-allocates memory, set breakpoints at the start and end of the operation (or step through the operation) to find the exact point that memory changed. Open the project you want to debug in Visual Studio and set a breakpoint in your app at the point where you want to begin examining memory usage. _declspec(allocator) void* myMalloc(size_t size) Collect memory usage data If you are writing your own allocators, then any functions that return a pointer to newly allocated heap memory can be decorated with _declspec(allocator), as seen in this example for myMalloc: Allocators in the CRT and Windows SDK have been annotated at the source level so that their allocation data can be captured. In many cases, the performance bottleneck of your application may be caused by something other than your memory, such as CPU, rendering UI, or network request time.Ĭustom Allocator Support The native memory profiler works by collecting allocation ETW event data emitted during run time. If Memory Usage does not give you the data that you need, other profiling tools in the Performance Profiler provide different kinds of information that might be helpful to you. Windows 8 and later is required to run profiling tools with the debugger ( Diagnostic Tools window). NET development in Visual Studio, including ASP.NET, ASP.NET Core, native/C++ development, and mixed mode (.NET and native) apps. The debugger-integrated Diagnostics Tools are supported for. Performing those actions while your app is running can eliminate the noise from the code that doesn't interest you and can significantly reduce the amount of time it takes you to diagnose an issue. Setting breakpoints, stepping, Break All, and other debugger actions can help you focus your performance investigations on the code paths that are most relevant. For more information, see Run profiling tools with or without the debugger.Īlthough you can collect memory snapshots at any time in the Memory Usage tool, you can use the Visual Studio debugger to control how your application executes while investigating performance issues. You can also analyze memory usage without a debugger attached or by targeting a running app. The Memory Usage tool lets you take one or more snapshots of the managed and native memory heap to help understand the memory usage impact of object types. Find memory leaks and inefficient memory while you're debugging with the debugger-integrated Memory Usage diagnostic tool.
