[Mono-winforms-list] System.MissingMethodException -- get_DefaultFont!

[Sebastien Pouliot]

Hello,

System.Drawing.SystemFonts.DefaultFont exists since 2005 (but it's a 2.0
class). 

I got the feeling you added a reference to 2.0 System.Windows.Forms.dll
(from the GAC path you provided) from a 1.x project (since you said you
*tried* to target 2.0) - which is *bad*.

Either use 1.1 or 2.0 for your projects but don't mix them (and live an
happy life ;-)
