Not Building Simple Hello World about cocoa-sharp-dev HOT 3 OPEN

I get exactly the same thing.

Also, I noticed in the video demo that Mono starts up apparently as a native 
application (it has "Mono" next to 
the blue apple symbol at the very top-left of the Mac's screen).  I have never 
seen that before when using Mono.  
Is there some connection between these two things?  Do we first need to get 
Mono working in this way before it 
will work with XCode?

Having used a previous version of this I was very surprised that I could not 
get it working.

This is the point the plugin was renamed

A quick search revealed that the Resources/Info.plist file still contained 
references to CSharpPlugin instead of 
CSharpXcodePlugin.
Changing this and rebuilding the plugin appears to resolve the problems.
(I am not sure about the one line though - com.mono.Xcode.CSharpPlugin

This appears to be fixed in 0.3.1 - thanks!
