Profile WinRT Application

WinRT applications are applications that use Windows Runtime framework. More specifically, these are Windows Store and Universal Windows Platform (UWP) applications.

Note that dotMemory is unable to profile a UWP application if it uses .NET native tool chain. To profile such an application, you should disable the Compile with .NET Native tool chain option in Visual Studio (via the menu Project | Properties... | Build) and rebuild the project.

To profile a WinRT application

  1. Run dotMemory as a standalone application. The dotMemory Home window will open.

  2. Add a run configuration - the configuration that tells dotMemory how to run the profiled application:

    • Under Choose what you want to profile, New Process Run, click Add run configuration Add run configuration.

    • In the New Run Configuration wizard, choose WinRT Application and click Next.

    • Specify application options:

      • In Packages, choose the application you are going to profile. If the application you are looking for is missing, click Refresh to update the list.

      • In Set environment variables specify the required environment variables. Each variable must be specified on a new line.

    • Click Save.

  3. Make sure the created run configuration is selected in the New Process Run list.

  4. Optionally, if your application creates a number of processes and you want to profile only specific ones, create process filters.

  5. If you want dotMemory to start collecting the stack trace allocation data * right after you start the session, under Run profiling, select Collect memory allocation and traffic data from start.

  6. Click Start. This will start the profiling session.

  7. Go through a particular workflow in your application (if you want to check it on potential memory issues) or reproduce a particular memory issue. Collect memory snapshots using the Get Snapshot button. Learn more about how to control the profiling session

  8. After you collect the data, either close the profiled application or detach the profiler using the Detach button.

  9. Analyze the collected snapshots.
