A WinForms app should work fine on Mono. Also,
"Application.EnableVisualStyles" is certainly supported. So, I do not think
that the previous reply about missing functionality is correct. I suspect
that your installation of Mono is simply incomplete or misconfigured.
To be honest, I have always compiled Mono from source on CentOS. Building
'libgdiplus' is a pain the first time because of all the image format
support dev packages you need to install (although those are all just 'yum
install' away) but Mono itself builds like a champ with a simple '/configure
&& make && make install'.
If I recall, the only dependency I needed to install to build Mono was
'bison'. That assumes that you already have 'gcc', 'libtool', 'automake',
'autoconf', 'pkgconfig', and the like installed though I suppose.
Regardless, you only need to install the supporting packages once and then
building it is a breeze every time after that. I build Mono from source on a
CentOS box just this morning.
I do not know how the packages work. Is it possible that you have installed
the assemblies for CLR4 but not the ones for CLR2. It is the Version=22.214.171.124
version of System.WIndows.Forms that your app is trying to call. Is there a
CLR2 version of 'mono-winforms' or does that package install both versions
of the framework?
Does this app work on Windows? Does it work on Mono elsewhere? Is it
possible to compile it as a .NET 4 app?
