Hi, I've been learning C# for a while now so I decided to finally tackle WPF, and I feel like a beginner again. Only a few pages into my studies I tried to replicate the code in my book but it just doesnt seem to produce the output that the book shows.
Im trying to create a simple window with a button as its only content, however the button is not showing up at all, just the window.
Also, the title of the window that pops up is "MainWindow" even though I called the constructor with the title argument "My First WPF Program"
Can somebody please help me resolve those 2 issues.
class Program : Application
Program app = new Program();
app.Startup += AppStartup;
app.Exit += AppExit;
static void AppStartup(object sender, StartupEventArgs arg)
MainWindow themain = new MainWindow("My First WPF Program", 400, 300);
static void AppExit(object sender, ExitEventArgs arg)
Console.WriteLine("Application is now exiting");
class MainWindow : Window
private Button exitbutton = new Button();
public MainWindow(string t, int h, int w)
exitbutton.Click += exitbutton_Click;
exitbutton.Content = "Close Window";
exitbutton.Height = 25;
exitbutton.Width = 100;
this.Content = exitbutton; // Setting content of the Window to a single button.
this.Title = t;
this.Height = h;
this.Width = w;
this.WindowStartupLocation = WindowStartupLocation.CenterScreen;
private void exitbutton_Click(object sender, RoutedEventArgs arg)
