Does WPF use dispatcher.begininvoke method for user interface?

Question

I have a WPF application that uses multiple threads. I'm curious to know if you are calling the UI thread using the Dispatcher.BeginInvoke () method, which is considered thread safe? Normally, I would use a lock statement to make sure that only one thread can access a variable. Will the following be in a streaming secure WPF application?

this.Dispatcher.BeginInvoke(() =>
{
    _counter ++;
});

Answer 1

The method Dispatcher.BeginInvokewill execute its callback in the dispatcher thread (typically a user interface thread if you don't have multiple dispatchers)

, counter , .
