[MonoDevelop] Projects will not run...

[Gareth Douglas]

Hi,

When I build and run my project in monodevelop it says:

"Cannot open assembly <executable name>"

I have tried to build and run a simple "Hello World" project and the same
happens.

I have also tried to use the gmcs compiler at the command prompt to compile
and once again face the same message when I try to run the executable.

Have any of you run into this before?

I couldn't find anything similar on the web.

Thanks for your help,
Doug
