How to disable button during it's binded task excute?

If you're using Mvvm Toolkit, this happens by default as AllowConcurrentExecutions is false by default. eg.

[RelayCommand]
public async Task DoTheThing()
{
    await Task.Delay(2000);
}

<Button Command="{Binding DoTheThingCommand}" Content="Click" />

Otherwise, you need to: manage some state within the body of the command (eg. bool IsExecuting), have your command implementation raise CanExecuteChanged, do your task, reset state, raise CanExecutiveChanged again so the button is re-enabled. Might be a cleaner way, but depends on ICommand implementation.

If you're using events (eg. Click) instead of commands here, then you toggle IsEnabled for the button in the event handler.

If you are using ReactiveUI this also happens by default when using one of the ReactiveCommand.Create() methods.
