Hi, @Jean-RochSDX I opened a PR that fixes it, but as @pjcollins suggested it is better to override the alert button's colors in styles like this:

<?xml version="1.0" encoding="UTF-8"?>
<resources>
    <style name="MyAppTheme" parent="Maui.MainTheme.NoActionBar">
        <item name="alertDialogTheme">@style/MyAlertDialogTheme</item>
    </style>

    <style name="MyAlertDialogTheme" parent="ThemeOverlay.MaterialComponents.MaterialAlertDialog">
      <item name="colorPrimary">@color/colorPrimary</item>
    </style>
</resources>

Therefore, I've closed that PR.

Thanks to it we can by default adjust the button colors to the app theme so that they look good in both the light and dark mode.
