If you have not downloaded Visual Studio Express IDE, you can download it from this link.
Launch the Visual Studio and select New Project.
Select Visual C# Wpf Application as in the screenshot below.
You might also want to name this application as Wpf.
Once you have created the Wpf application, you will see a window similar to the screenshot below.
In the Visual Studio, you can see that it has already created for us MainWindow.xaml and MainWindow.xaml.cs.
The MainWindow.xaml is the main xaml file and the MainWindow.xaml.cs is the so called C# code behind file.
Click on the start button or key in F5 and you will see that an empty window is created. This doesn’t do much and I know.
