Threads.join() doesn't work like expected

Question

Hi, I am totally new to C# and doing a retraining.

 

Today I walked into a little problem I can't solve yet.. 

 

I did a tutorial from Pragmtech on youtube: 

 https://www.youtube.com/watch?v=SgHYVPKJRX8&list=PLAC325451207E3105&index=102

 

 

The problem is that  when running the code it doesn't show the text "processing file. Please wait".  

 

I hope someone can help me out. Thx!

 

private int CountCharacters()
        {
            int count = 0;
            using (StreamReader reader = new StreamReader(@"C:\Users\TTTG11133.NOA\Documents\JeroenK\Test\AsyncAwaitPragmTech101\data.txt"))
            {
                string content = reader.ReadToEnd();
                count = content.Length;
                Thread.Sleep(5000);
            }
            return count;

        }


        //Async await with blocking (using task)
        private async void btnProcess1_Click(object sender, RoutedEventArgs e)
        {


            Task<int> task = new Task<int>(CountCharacters);
            task.Start();

            lblCount.Text = "processing file. Please wait...";
            int count = await task;

            lblCount.Text = count.ToString() + "characters in file";
            myTextBox.Text = "jeroen";

        }

private void btnProces2_Click(object sender, RoutedEventArgs e)
        {

            int count = 0;

            Thread thread = new Thread(() => { count = CountCharacters(); });
            thread.Start();

            myTextBlock2.Text = "processing file. Please wait...";
            thread.Join(); // The next string should appear after  5 sec.
            myTextBlock2.Text = count.ToString();




        }
