[Mono-winforms-list] Getting the latest winforms code to run on linux

[Sebastien Pouliot]

Hello Dan,

It is a message from libgdiplus (*)

As a general rule you cannot update SWF without updating System.Drawing,
and you cannot update System.Drawing without updating libgdiplus. 

While you can break this rule 90% of the time, you'll end up (10%) in
hard to diagnose bugs (or cosmetic issues) that no one else can
duplicate. Once there it's easy to lose much more time finding the
(non-)bugs than to update everything, every time.

(*) In this case the message means it could not decode an image. From
the stacktrace I'm pretty sure this is due to an old libgdiplus that
didn't implement the ICO codec with a newer System.Drawing.dll (that no
longer use managed code for this task).
