[Mono-winforms-list] newbie questions trying to get winforms working

[Peter Dennis Bartok]

Dan,

Your questions aren't really winforms specific, so 
mono-list at lists.ximian.com might be a better place to ask.

However, yes, it is correct that there are multiple versions of the 
libraries. One for the .Net 1.1 Framework, and one for the .Net 2.0 
Framework.

When compiling, don't specify the whole path. Simply saying
"mcs ... -r:System.Drawing.Design.dll"
is enough, it will pick the appropriate assembly. When you want to use the 
2.0 versions, you need to use the 2.0 compiler, gmcs. In other words,
"gmcs ... -r:System.Drawing.Design.dll"
will use the 2.0 versions of the assemblies (and you get to use all the 
features that were added for .Net 2.0 to the language, like generics, as 
well as the 2.0 methods and properties of each assembly)

You also usually don't need to set the path, it's all triggered by which 
compiler (mcs or gmcs) you use.

Cheers,
 Peter
