[Bug] LongPressCommand not working in UWP

[Sergtek]

Description

The LongPressCommand does not work in UWP, however on Android, iOS and macOS it works correctly.

Steps to Reproduce

1. Add LongPressCommand in some control and bind the property to a command in the view model, it works on Android, iOS, and macOS but not UWP.

<Label Text="Long click"
            TextColor="Black"                                  
            FontSize="Small"
            xct:TouchEffect.LongPressCommand="{Binding TestCommand}"
            xct:TouchEffect.LongPressDuration="900"/>

Expected Behavior

When the user makes a long click on the control, the binded command should be executed.

Actual Behavior

When you hold down a control the time defined in LongPressDuration in UWP nothing happens.

Hi @Nacompllo thanks for the report
Does regular Command work?

if not, then try to add

var assembliesToInclude = new List<Assembly>()
{
    typeof(Xamarin.CommunityToolkit.Effects.TouchEffect).GetTypeInfo().Assembly
};

Xamarin.Forms.Forms.Init(e, assembliesToInclude);

to your UWP code

Hi, the normal command doesn't work in UWP either, not even if I include the assemblies in App.xaml.cs.

@Nacompllo play with the minimum/target version. There was a problem with that, i don't remember exactly what versions are needed, @AndreiMisiukevich remind please

I have tried several combinations but it seems that it does not work either, at the moment the only solution is to stay in version 1.0.3 which is the last version where it works.

@jfversluis @pictos what is the minimum required version for UWP?

[AndreiMisiukevich]

Try to set UWP higher UWP version like described here #1247

I am pretty sure it's not TouchEffect issue (just need to set a proper UWP version)

[pictos]

@AndreiMisiukevich if the issue is the caused by UWP version, that should be fixed in the next stable release.

[AndreiMisiukevich]

Can anyone check if toucheffect works fine on UWP with our sample app?

[pictos]

@AndreiMisiukevich yes it's working. (main branch)

[AndreiMisiukevich]

@pictos can we advise some workaround for now and close this issue?

[pictos]

@AndreiMisiukevich may be saying that this is duplicated from #998 or any other UWP target issue and close this one...

IMHO we can close this one since we have other issues tracking this problem.
