MAUI App .NET 10 RC2 new project bundle size is around 1 MB larger than .NET 9

[trivalik]

Description

This is follow up issue to dotnet/maui#31316

I have created default template app project in both .NET9 and .NET 10 preview 7 (see other issue). Now I recreated for .NET 10 RC2 (include in visual studio 2026 Insider 11111.16)

   <AndroidPackageFormat>apk</AndroidPackageFormat>
    <TrimMode>full</TrimMode>

into csproj file.

The size is still bigger than NET9 24,249 KB. .NET RC2 size is now 25.198 KB, so 100 KB less to .NET 10 preview 7.

Steps to Reproduce

Create new MAUI projects on System with .NET 9 and create a new MAUI project on Systems with .NET 10 RC2. Then compare the release output, in my case apk.

The app above is built for two architectures. If you are distributing for Google Play, the app store knows how to split this up per device when you submit an app bundle.

Did you compare if our changes improves anything in .NET 10 RC 2 since the last time you filed this?

You can try the new AndroidStripNativeLibraries property in your .csproj.
