Below is a guide for profiling a Windows .NET MAUI application from:

Profiling .NET MAUI AppsGitHub

Windows & PerfView

PerfView is probably the simplest way to profile a .NET MAUI application running on Windows. We recommend using a Release build with ReadyToRun enabled. See our Windows Publishing Documentation for details about building a Release version of your app.

Begin by selecting the Collect > Collect menu. For a project named hellomaui, you can filter on hellomaui.exe:

PerfView Collect Screen

Click Start Collection and manually launch your app.

Click Stop Collection when your app has launched and reached the point you are finished profiling.

Open CPU Stacks to view timing information of methods inside your app:

PerfView CPU Stacks

Use the Flame Graph tab for a graphical view:

You can also do File > Save View As to save the file in SpeedScope format. This allows you to open the file in https://speedscope.app/ as we recommend for iOS/Android projects.

Windows & dotnet-trace

You can get a .nettrace or .speedscope file by publishing your app "unpackaged":

dotnet publish -f net6.0-windows10.0.19041.0 -c Release -p:PublishReadyToRun=true -p:WindowsPackageType=None

Then run dotnet-trace against the published .exe:

dotnet trace collect -- bin\Release\net6.0-windows10.0.19041.0\win10-x64\publish\YourApp.exe

This will place a .nettrace file in the current directory. You can also use --format speedscope to open the file in https://speedscope.app/.
