Summary0000302: Add support for multiple platforms using the Mono Framework (Linux, OS X, iOS, Android)
DescriptionMono is a C# cross platform open source implementation of .NET. It supports WinForms. http://www.mono-project.com/Main_Page [^]

Converting to Mono would make the application work on Linux and Mac OS X, *IF* the third party libraries can work on those platforms. They all theoretically support these platforms, but that doesn't mean they work under Mono on those platforms.

I ran the MoMA test (Mono Migration Analyzer) and it seems that converting to Mono wouldn't be that bad after all. The errors it gave are 98% because of using the Win32 version of bass.dll (P/Invoke). According to this thread (http://www.un4seen.com/forum/?topic=7260.0;hl=mono+linux [^]) if the Linux version is used, there are no P/Invoke problems.

-------

The prototype is sufficiently advanced to say that a Mono version will be done!

The Async framework and Reactive Extensions might not work at all under Mono.

After some testing, I was able to do a very simple prototype with the BASS library. It indeed works using Mono on Linux and Mac OS X.

The next step is deciding on a UI framework. Technically, Mono supports Windows Forms but when I tried to run MPfm on Mono, the designer.cs files gave a lot of errors. The SplitContainer does not seem to be supported.

So maybe WinForms can be kept for Windows, but GTK could be used for Linux and Mac. MonoMac + Cocoa can be used for Mac too; it doesn't require a UI framework to run, only Mono installed. The native controls are used instead. However, that would mean a different UI toolkit for each platform.

I'm also looking at what can be bundled as an app for the Mac App Store (Mono, GTK). If GTK can be used, that could be a better idea than having 3 different UI toolkits.

Mono supports SQLite natively for .NET 4.0. The code seems slightly different than what is used in Windows though, so maybe an interface should be added to the Gateway class.

I've pushed the prototype further and now the Player class is 90% functional under Mono. The gapless playback and sync points work so far on Linux.
