Migrating from Visual Studio to CodeBlocks

[Mathend99]

Hi!, guys. Sorry to bother you. I need a little help.
I wrote a small, working, application using Microsoft Visual C++/CLI and I now have to have it run under Ubuntu.
First, I created an empty project in CodeBlocks and added all of the old files to it (*.h, *.cpp, etc.).
After days of trying this and that to build it, the compilation is down to two errors:
* expected unqualified-id before 'public'
* expected '}' at end of input
I have checked the files and done a fair amount of searching, but no luck.
By the way, when I said "this and that" it means I commented out statements like "using namespace System" and "#pragma once" that were giving me errors.
Can you guys help me or point me towards the appropriate documentation"
THANKS IN ADVANCE!!!

Do you see somewhere in this page any info about a non-MS compiler which supports C++/CLI?
