RoutedEventArgs cannot be founded in the System.Windows

Question

I have a program on the Windows Forms (VS13). In the code:

using System.Windows;

namespace WF
{
    public partial class Form1 : Form
    {
        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            //...
        }
    }
}

RoutedEventArgs cannot be found, but it exists in the namespace System.Windows. What can be reason? I have a reference to the WindowsBase.

Answer 1

RoutedEventArgs is a WPF-specific thing. In Winforms, nothing like that exists. You should remove your reference to WindowsBase ans stick to Winforms specific things.

For instance, the Loaded event doesn't exists. You must use the Load event from the Form object instead. The designer really helps here in adding all the bits of code you need and attaching the event handlers.
