Awesome

TouchEffect was merged into XamarinCommunityToolkit https://github.com/xamarin/XamarinCommunityToolkit/pull/566 I highly recommed to use TouchEffect from XCT

TouchEff effect for Xamarin Forms (Repsonisve touches without TapGestureRecognizer)

This plugin provides opportunity to create views with touch effects without using TapGestureRecognizer. It makes it possible to change the appearance of any control in response to touch events, either directly via xaml or with your custom logic hooked up to the events which this plugin exposes.

With this plugin it is also possible to respond to hover events (if the platform exposes them) and to display native touch feedback events (Tilt on UWP, Ripple on Android, Opacity/Color changing on iOS).

Xamarin.UWP - Build on Release with .NET Native tool chain note

using System.Reflection;
...
var assembliesToInclude = new List<Assembly>
{
    typeof(PlatformTouchEff).GetTypeInfo().Assembly,
    ...
};
Xamarin.Forms.Forms.Init(e, assembliesToInclude);

XAML: use TouchEff for achieving repsonsive UI (Changing background image or/and background color or/and opacity or/and scale).

Use TouchEff attached properties for setting up touch visual effect.

...
  xmlns:touch="clr-namespace:TouchEffect;assembly=TouchEffect"
...
       <ContentView
            touch:TouchEff.PressedAnimationDuration="800"
            touch:TouchEff.RegularAnimationDuration="800"
            touch:TouchEff.PressedScale="0.9"
            touch:TouchEff.PressedOpacity="0.6"
            touch:TouchEff.RippleCount="-1"
            touch:TouchEff.Command="{Binding Command}">
            
            Padding="10, 5"
            BackgroundColor="Black"
            VerticalOptions="CenterAndExpand"
            HorizontalOptions="CenterAndExpand">
            
            <Label Text="CLICK ME" 
                   TextColor="White" 
                   FontSize="60"/>
            
        </ContentView>
...
       <StackLayout
            touch:TouchEff.RegularBackgroundColor="Green"
            touch:TouchEff.PressedBackgroundColor="Red"
            touch:TouchEff.PressedScale="1.2"
            touch:TouchEff.RippleCount="1"
            touch:TouchEff.PressedRotation="10"
            touch:TouchEff.PressedRotationX="15"
            touch:TouchEff.PressedRotationY="15"
            touch:TouchEff.PressedTranslationX="5"
            touch:TouchEff.PressedTranslationY="5"
            touch:TouchEff.PressedAnimationDuration="500"
            touch:TouchEff.RegularAnimationDuration="500"
            touch:TouchEff.Command="{Binding Command}">

            Padding="10, 5"
            VerticalOptions="CenterAndExpand"
            HorizontalOptions="CenterAndExpand">

            <Label Text="CLICK ME" 
                   TextColor="Black" 
                   FontSize="60"/>
        </StackLayout>

If you wish to change Image Source on touch, you should use TouchImage control. It has several bindable properties for managing Pressed/Regular Source/Aspect of the image.

...
  xmlns:touch="clr-namespace:TouchEffect;assembly=TouchEffect"
...
       <touch:TouchImage
            VerticalOptions="CenterAndExpand"
            HorizontalOptions="CenterAndExpand"
            HeightRequest="250"
            WidthRequest="250"
            RegularBackgroundImageSource="button"
            PressedBackgroundImageSource="button_pressed"
            touch:TouchEff.Command="{Binding Command}"
            />
