[Mono-list] Moving from Mono/C# from C/Linux world

Tue Mar 7 16:53:42 EST 2006

ISV adoption is going to take a while in my opinion. .NET guys are mostly
windows guys, and at the moment VS.NET 2005 is considered superior to mono
on MS platforms. Most *nix people that would use .NET are already Java guys,
and most of them probably see little reason to switch from Java.

Personally I would love to be able to use mono on *nix and therefore escape
windows-land, however until mono matures some I don't think there's a good
reason to use it over .NET2.0 in a production environment. That said, if I
ever have a client that needs both MS and *nix support I wouldn't have any
problem using mono/.net1.1

.Net and therefore Mono is a complete platform/framework whereas
it sounds like you use the more traditional C/Unix environment of C as 
the language, and Unix as the platform.  There's no reason you can't use 
the same development methodology with Mono (small apps, shell ties them 
together), but I think you'll be disappointed with the performance.

IMHO Mono will work much better if you work toward adopting it not just 
as a language, but as a framework.  Use remoting instead of sockets and 
pipes.  Write larger applications, so you don't have to tie them 
together with shell scripts.  And definitely encourage good OO 
programming techniques so that your entire organization can reuse code 
and build a common internal framework.

This is just my $0.02.  I'm not saying Mono won't work as a drop-in 
replacement for small C apps.  I'm just saying thats not where its 
strengths lie.

This seems to be a pretty common fear, but I think you can be at ease
about the longevity of Mono.  First of all subscribing to the mono-devel
list will give you a good idea of how quickly mono is progressing.  Also
Mono has a major corporate backer, Novell.  While Novell has seen better
days, they're not going away anytime soon, and they've completely
committed to Linux and Mono as their platform.

For the most part, the free and open source software world has accepted
Mono after some trepidation.  Popular databases distribute Mono specific
interfaces, and many popular Java projects have been ported (such as
(N)Hibernate or iText#).  RedHat's Fedora distribution even includes
Mono now, even though RedHat remains very committed to Java in the
enterprise (vs. Mono/.Net).

Also, the ECMA specifications themselves seem to be constantly
improving. There were lots of exciting language and framework improves 
in .Net 2.0, and lots of interesting work being done for 3.0.

The main area I see Mono acceptance as being slow is ISVs, and thats
because they're probably using Microsoft .Net, C++, or Java as their
development environment.  I think as Linux continues to gain market
share and the support of ISVs, you'll see more ISVs choosing .Net & Mono
as their cross platform development framework.  However, thats largely
speculation, and there's a pretty good argument for Java
staying/becoming dominant in the cross platform space.
