DispatcherHelper in Windows Community Toolkit

I am working on upgrading MVVMLight to Windows Community Toolkit and facing issues with DispatcherHelper. I am unable to find any examples which can show me how to upgrade the functionality relating to DispatcherHelper. Any pointers will be really appreciated.

Hi,@AnilChanna-0773 . Is your project a wpf project or a uwp project? Could you show some code and details related to your problem?

Mine is WPF project developed using .Net Framework 4.5 and I am working on upgrading it to .Net 6. I am unable to understand how to use Dispatcher Helper in Windows Community Toolkit. Here is one example of the code to be modified -

DispatcherHelper.CheckBeginInvokeOnUI(() => { toRemove.ForEach(x => this.ProjectFiles.Remove(x)); });

Here is another example which needs to be converted -

        this.timer = new DispatcherTimer(DispatcherPriority.DataBind, DispatcherHelper.UIDispatcher)
        {
            Interval = new TimeSpan(0, 0, 1),
            IsEnabled = true
        };

I am unsure how to achieve this using Windows Community Toolkit
