Prevent the application from freezing

If the extension executes a process that takes a long time, the application may appear to freeze. The following code allows you to draw the UI while the extension is running.

using System.Windows.Threading;

///<summary>
///DoEvents
///</summary>
void DoEvents()
{
    var frame = new DispatcherFrame();

    var callback = new DispatcherOperationCallback(obj =>
    {
        ((DispatcherFrame)obj).Continue = false;
        return null;
    });

    Dispatcher.CurrentDispatcher.BeginInvoke(DispatcherPriority.Background, callback, frame);
    Dispatcher.PushFrame(frame);
}

void SomeCommand(ICommandContext c, ICommandParams p)
{
    for (var i = 0; i < 100; i++)
    {
        //Do some processing
        ...

//Update the application screen
DoEvents();
    }
}

Caution

Instead of blocking the user interface, it is possible to operate the screen, which may result in unexpected behavior, so please use with caution.
