A very basic explanation for threading in WPF?

Question

I am very very new to WPF. I looked in the internet for several examples and tutorials about threading. They\'ve their own way to describe. But for naive like me, I want to

Answer 1

1. Multithreading hasn't anything to deal with the UI techinque you are choosing (Wpf or Winforms) - there are only slight differences when you have to switch to the UI thread to update your controls.

2. According to your code sample, I must say, that there is no callback possibility from sql server to your program. If you want to have that feature, you have to implement the loop in C# not in a sql statement.

Edit:

According to the comment of OP I add a sample of background working and updating UI in foreground with TPL (Task Parallel Library):

var task = new Task(() =>
    {
        // Do something very long ...
    });

task.ContinueWith((previousTask) =>
    {
        label.Content = "Background work has finished.";
    },
    TaskScheduler.FromCurrentSynchronizationContext());

label.Content = "Background work is running.";
task.Start();
