Starting in mono and c#

[mgazb]

I'm just starting learning c# and mono. I've written a command line hello world but am having trouble with a GUI version.

If I add


using System.Windows.Forms;


then mcs fails to compile it. It can't find dotnet if I add it to the command line.


dwhs1@gloin:~/mono$ mcs /pkg:dotnet blah.cs
Package dotnet was not found in the pkg-config search path.
Perhaps you should add the directory containing `dotnet.pc'
to the PKG_CONFIG_PATH environment variable
No package 'dotnet' found


Where can I get the dotnet package?

If I explicitly include the forms library


mcs -r:/usr/lib/mono/gac/System.Windows.Forms/2.0.0.0__b77a5c561934e089/System.Windows.Forms.dll blah.cs


I get a different lot of errors.

Is there a way of including winforms in a mono build?

you'll need to compile your code in this way


mcs blah.cs -r:System.Windows.Forms.dll -r:System.Drawing.dll

Thanks for the reply, it has got me the next step forward.
I had to add



dwhs1@gloin:~/mono$ export MONO_PATH=/usr/lib/mono/2.0


to get it to find forms and drawing. I suspect that this demonstrates that I don't have everything set up correctly.



dwhs1@gloin:~/mono$ mcs -r:System.Windows.Forms.dll -r:System.Windows.Drawing.dll -r:System.Diagnostocs.dll blah.cs

where can I find System.Diagnostics? I have grepped the /user/lib tree and still can't find it.

thanks

If I use gmcs, then everything seems to work and I don't even need to reference System.Windows.Drawing and don't need to change MONO_PATH.
