Great News! Mono here we come...

Just got through installing Ubuntu.

I expect to see some really good software come out of this. I think Microsoft bought a lot of goodwill with the community with this move.

Any ideas why the compilation is so slow? Compiling a simple "Hello World!" takes a noticeable amount of time on my reasonably well endowed laptop(i5, 4GB ram).

Is it slow just on linux/mono or that's the case on windows as well?

Other than the compilation time, all else seems well. I was following "Programming F#" and didn't run in any blockers on selective examples I tried. Once compiled, the performance is reasonable.

The compiler and interpreter aren't pre-compiled. Use the --resident flag - it will keep the F# compiler running as a service.

Thanks for the tip, the slowness of the F# compiler under mono was bugging me too.

Miguel has left a very suspicious tweet:

"There is a rumor on the tweetosphere of an F# addin for MonoDevelop being demoed tomorrow ;-)"

This is very exciting!

There is actually an F# package for Mono (Linux/Mac) already: http://fsxplat.codeplex.com/ Although, the current release of F# has some bugs when running on Mono - open source release opens some cool possibilities :-)

It already runs under Mono - though, a few parts are a bit buggy.

The release comes with a script to install it on Mono:
