I am seeing the same effect here:
case=40179
I was able to reproduce this via using a button:
1. Placed a button on the "form" or whatever it is called so I got button1
2. I wrote button1.Click +=
and got this with Visual Assist disabled
button1.Click += new RoutedEventHandler(button1_Click);
and a new function
void button1_Click(object sender, RoutedEventArgs e)
{
throw new NotImplementedException();
}
With Visual Assist enabled I got
button1.Click += new button1.Click
This is a good start. But can you please explain what handler did you use? (by step-by-step please, since I am not a WPF expert )
I will add your steps to the bug report as an additional test case, just for sure.
