By the way you can grab much newer builds of mono and monodevelop by following

http://www.mono-project.com/docs/getting-started/install/linux/#debian-ubuntu-and-derivatives

and

I'm using Monodevelop 5.7.1 which is considerably newer than what
you're using but for this version, the .NET target framework version
is set for each project and not on the solution. So I can can right
click on a project in my solution, select "options" and then under
"Build > General" I can pick the target framework.

Debian (and hence Ubuntu) likes splitting projects like mono into many
separate packages so you might have forgotten to install the one for
web helpers (if there is one). I think the "mono-complete" package
will install everything.

Hope that helps.
