Mono® Migration Analyzer (MoMA)

• Inspects CIL byte code

• Looks for uses, compares with implementation

– Missing methods

– Unmanaged Calls

– “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

14

Develop Anywhere - Deploy Anywhere

• Mono includes a toolchain for Linux

– command-line C# & VB compilers

– MonoDevelop IDE

– Much More...

• Mono's runtime is also binary-compatible with .NET on Windows

– Use Visual Studio IDE to Develop, Compile, and Debug code

– Take advantage of tools available in the .NET ecosystem for profiling, static analysis, etc.

– Deploy to Linux, OS X, etc


15

Commercial Mono®-based Apps

• Patient information system

• 3D game modeling tool

• Windows to Linux migration tool

• Test automation software

• Managed office wiki

• Instant messaging & social networking

• Cross-platform CRM

• Embeddable SQL database engine

–Hundreds of application developed using Mono, including:

Case Study: Graffiti CMS

• Who– Telligent – Creators of Community Server

• Business Challenges– Windows-only solution limited market reach– Established competitors provide cross-platform offerings

• Mono Solution– Support for ASP.NET 2.0

> Host with apache or fastcgi servers

– Multiple Database backends> VistaDB

> MySQL

> SQL Server

> Access

17

Case Study: Codice

• Who– Developers of PlasticSCM configuration management– Extremely competitive market– Tradeoff between high-end expense and low-end functionality– Bring high-end SCM technology to small/medium software teams

• Business Challenges– Windows-only solution limited market reach– High-end features available and affordable on multiple platforms, while still

being easy to install and use– Advanced features like branch handling and security settings, without

imposing development restrictions– As powerful as Clearcase, easy to use, fast and affordable to any-sized team

• Mono Solution– Advanced features of C#– Single code-base for Windows/Linux– Fast time to market

18

Mobile Devices

• Sansa Connect– First Wi-Fi™ based MP3 player from

SanDisk’s audio line; plays music, photos and Internet radio

– Running Linux, entire application stack is built on Mono, running on an ARM processor

– Developed by zing.net

– “Best in Show” at CES

I've been doing stuff like this for the past 4 or 5 years, I've been doing stuff like this for the past 4 or 5 years, and I can definitely say that mono is WAY better than and I can definitely say that mono is WAY better than MSFT's .NetCF.”MSFT's .NetCF.”

Case Study: Second Life

• Who– 3-D virtual world entirely built and owned by its Residents– Inhabited by 9,333,833 Residents from around the globe

• Business Challenges– As of August 2006, 3000 computers, growing at 300 machines/month– 12,000 distinct scripts, 3 million lines of script code (user code)– Current scripting language LSL running out of steam

• Mono Solution– High performance JIT VM– Existing LSL code JITed and optimized by Mono engine and run at native speeds– Gives developers the flexibility they need in using the LSL language– Opens the doors to the Second Life developers to use other CLI languages like C#,

Boo, Python or JavaScript side-by-side.– 50 – 150 times faster– Less than 50% of the memory use

http://www.secondlife.com


20

Case Study: Otee

• Who– Creator of the Unity 3D game development system– Used by leading game development studios worldwide– "Best Use of Mac OS X Graphics" at Apple's World Wide Developer Conference

• Business Challenges– Python for scripting becoming too slow and unwieldy for growing code base– New solution had to be very fast because game code runs in real-time– Had to be portable to support making games for multiple platforms– Wide range of developer backgrounds, programming languages– Had to be easy to understand, accommodate wide range of users and skill levels

• Mono Solution– Allowed OTEE to give developers a choice between JavaScript, C# and Boo– Very short learning curve and immediate familiarity with scripting in Unity– Mono scripting provides power to create complex game logic, without sacrificing

performance.– Unity now enjoys a rapidly growing user base on both Windows and Mac OS X

– ~4Mb footprint for basic setup (uncompressed).

– Allows C code to call managed code.

– Allows managed code to call into main application.

• Fast:

– JIT engine provides the speed.

– Choice of languages.


24

Mono Licensing

• Can I write commercial or proprietary applications that run with Mono?

– Yes. The licensing scheme is planned to allow proprietary developers to write applications with Mono.

• We use three open source licenses:> The C# Compiler and tools are released under the terms of the GNU

General Public License (Moving to MIT X11 in Mono 2.0)

> The runtime libraries are under the GNU Library GPL 2.0

> The class libraries are released under the terms of the MIT X11 license.
