 Developing Windows applications using C# and WPF

  Course Code: GN-301   Duration: 5 Days 

This 5 day course covers the C# language and its use for Windows desktop applications using the Windows Presentation Foundation (WPF). Developing for WPF is interesting as it actually uses 2 languages simultaneously - C# for the functionality and XAML for the UI design. A shorter course can be provided if you are already familiar with C#, and several optional modules can be added to match your particular requirements.
