Cross-Platform .NET: Mono and MySQL Joseph Hill Product Manager for Mono, Novell jhill@novell.com Joe Audette Founder, Source Tree Solutions, LLC joe.audette@gmail.com

Multi-platform, Multi-language x86 C# Visual Basic SPARC Boo Java (IKVM) Common Intermediate Language Code Generation: Just-In-Time or Ahead-of-Time StrongARM F# JavaScript Interesting thing about Mono/.NET CIL (Common Intermediate Language): the "Lingua Franca" for computer languages. Allows you to write a front-end compiler (C#, Java, etc.) and instead of generating native machine code, you generate code for the intermediate language. So you always map to a single language, then the single language gets mapped to the target OS. We take the IL and generate code that will run on a number of platforms. So today we have very good coverage of languages that you can use with Mono. C# 2.0 (you can use full generics), VB.NET, Java applications - with IKVM which has been incredibly popluar - and a bunch of other languages. s390 IronPython IronRuby PowerPC

Mono® Migration Analyzer (MoMA) Inspects CIL byte code Looks for uses, compares with implementation Missing methods “Todo” methods (flagged with an attribute) MoMA is the best place to start; full report of how easy your existing app will be to migrate We started building the left side of the stack, ie, ASP.NET, ADO.NET, Windows.Forms, and that stack is done for 1.1 and 70% done for .NET 2.0. We can run a lot of apps with that. But we didn't really know what people were using, which controls, which bugs actually matter, etc. So, a couple of months ago we built a tool that people could run on windows, and would allow us to figure out what to implement. So we have developed this. Inspects the byte code, looks at methods, and ships with a definition of everything that Mono has. Generates a report and sends it to our website. Developers can use this tool to find out what apps are portable, and which apps are not portable. So, once the data is submitted, let's see what the data looks like. We aggregate all the data that people have sent us. Between Mono 1.2.2 and 1.2.3 we implemented 2000 methods. Regarding apps submitted to us, 16% are VB, 67% are Windows.Forms, 28% are .NET 1.1, and 72% are .NET 2.0. http://www.mono-project.com/Moma

Takes your Java byte code and xlates on the fly and generates code for the CIL. Has exploded into a universe of API and class libraries. Cecil - a library that lets you manipulate executabeles, insect, make mods, insert code, inspect code, etc. (Implementation of ECMA #335)
