Making a C#/Winform application cross-platform - should I use AIR, Mono, or something else?

Question

I have an app that I\'ve written in C#/WinForms (my little app). To make it cross-platform, I\'m thinking of redoing it in Adobe AIR. Are there any arguments in favor of Win

Answer 1

I asked a similar question last week. I've been using Mono all along, and have had no issues running the applications I compile to IL to run on SuSE linux (I usually run KDE) or windows, however, I've not gone out and got a mac yet to test it on. I will be soon, though, probably with in a couple weeks. But all and all development in Mono has been very good at creating application that will run on multiple platforms.

Why would you go with Air?

Use GTK#, and you have a cross platform forms engine and you get to keep your C# code.

I don't think there is a future for WinForms at all. Since it appears to have been a stop-gap solution even in MSFT world ( a very thin wrapper around Win32). And virtually no changes seem to have been made to System.Windows.Forms in both .NET 3.0 and 3.5

</speculation>

I would use Java or Air.

I think that as long as you make sure that the business logic code you write is cross-platform (i.e. using backslashes in paths only works on Windows - forward slashes works on all OS's), then Mono shouldn't have major problems running an unmodified WinForms program. Just make sure you test for graphical glitches.

If you want to use the .net Framework, Microsoft Silverlight is a good (the only?) choice. The browser does a good job as a shell, but you could also write your own application shell for it. For example, Scott Handelman mentions the NY Times Reader written in Silverlight and hostet on Cocoa on a Mac.

As far as my experience in Flex/AIR/Flash actionscripting goes, Adobe AIR development environment and coding/debugging toolsets are far inferior to the Visual Studio and .NET SDK as of the moment. The UI toolsets are superior though.

But as you already have a working C# code, porting it to ActionScript might requires a redesign due to ActionScript having a different way of thinking/programming, they use different primitive data types, for example, they use just a Number instead of int float double etc. and the debugging tools are quiet lacking compared to VS IMO.

And I heard that Mono's GtkSharp is quiet a decent platform.

But if you don't mind the coding/debugging tooling problems, then AIR is a great platform. I like how Adobe integrates the Flash experience into it e.g. you can start an installation of AIR application via a button click in a flash movieclip, that kind of integration.
