I repaired the Orcas install just in case but still no luck. I create a new WPF Application project, move the cursor to just inside the <Grid> tag in the Window1.xaml files created by default, and type "<". I s

However, once the client is installed on another machine it stops functioning.

      • I'd like to suggest a simple new property declaration syntax for C# 3 that would virtually eliminate property clutter while being highly flexible. The syntax would consist merely of a type, identifier and then an expression in braces. For example: int X { _x } The compiler would translate this to: int X { get { return _x.Value; } set { _x.Value = value; } } In order to compile, _x would have

If I then drag one of the leafs and move it to the top of the control it won't scroll up. You can find the same (working) behavior in windows explorer. Is this a limitation to the treeview or have i done something wrong
