1. Hacking Mono and .NET Atsushi Eno　　　　
2. I am... Atsushi Eno ex-mono developer Xamarin.Android developer http://goo.gl/OqqpfK
3. 開源版.NET Framework 実装 Open Source .NET Framework implementation 可以用在 runs on: Linux, Mac, Windows, iOS, Android ... 有自己的軟體生態系統 has own ecosystem Mono http://goo.gl/OqqpfK
4. 目的 Aims • .NET跟Mono開源程度? find how open source .NET and Mono are. • Mono未來開發走向會到哪裡? find where Mono development goes. • 你們可以在.NET/Mono上研究跟hack什麼? find what you can research and hack into. http://goo.gl/OqqpfK
5. .NET/Mono 軟體堆疊 software stack • Runtime [CLR, mono runtime] ◦ CIL metadata execution engine (JIT) ◦ 垃圾收集器　garbage collector ◦ 其他核心處理　other core operations • C# 編譯器　Compilers (etc.) [csc, mcs] 命令行編譯器　command line compiler 編譯器即服務　compiler as a service • 函式庫　Class Libraries
6. 開源程度.NET? / How is .NET open? 所以呢、它跟Mono有關係嗎? so what, does it matter for Mono?
7. 開源程度.NET? / How is .NET open? 所以呢、它跟Mono有關係嗎? so what, does it matter for Mono? →我們（可以）再利用他們的程式源碼、不要重新發明輪子 　We (can) reuse their code, no need to reinvent the wheel →我們可以修改、使其運行在Mono / *nix環境 　We can make changes to make it work on Mono / *nix
8. WinForms WPF
9. WPF WinForms Silverlight
10. WPF WinForms StoreApp Silverlight
11. WPF WinForms StoreApp Silverlight
12. Project Hosting • https://github.com/aspnet ◦ 包含 SignalR, EntityFramework etc. • https://github.com/reactive-extensions • https://github.com/fsharp • http://roslyn.codeplex.com/ • http://dlr.codeplex.com/ 你可以提交PR / You can submit pull requests!
13. Mono Framework ./mono ./mono - runtime ./mcs ./mcs - compiler ./class - class libraries
14. mono runtime, 虛擬機 VM - C CIL metadata loader (assembly loader) "mini" virtual execution system: JIT, AOT "sgen" garbage collector core operations string and numbers, I/O, threading, marshal, g10n etc. miscellaneous - profiler, debugger, security ./mono ./mono ./mcs ./mcs ./class
15. mcs: C# 編譯器 compiler - C# Full C# 5 support + some C#6 feature C# REPL (csharp, gsharp) NRefactory - compiler as a service code formatting code completion code analysys ... needs to work with Roslyn ./mono ./mono ./mcs ./mcs ./class
16. mcs 函式庫 Class Libraries per assembly: mcs/class/corlib, ../System, ... ADO.NET, ASP.NET, WinForms, WCF... not "complete" submodule Microsoft libraries. PCL profile assemblies too. ./mono ./mono ./mcs ./mcs ./class
17. Mono GUI Frameworks • Gtk# - Gtk+ .NET binding ◦ Banshee, F-Spot, Pinta ... • MonoMac - Cocoa binding • Xwt - cross platform UI toolkit ◦ WPF/MonoMac/Gtk# ◦ supports XAML ◦ Xamarin product uses it
20. MonoDevelop (Xamarin Studio) COSCUP 2013: MonoDevelop: how modern IDE and code editor works
21. Mono: 發展方向 dev. direction
22. Mono的情況 / Mono state of union Mono 1.0: .NET 1.1, core & server (ASP.NET) ".NET on Linux" Mono 1.2: .NET 2.0, WinForms & Gtk# apps "Linux desktop apps on .NET" Mono 2.x: .NET 3,5/4.0, Linq, dynamic, Silverlight Mono 3.x: .NET 4.5, mobile Mono team has been doing a lot (and some are dead)
23. 發展方向 Development Direction Mono core team - Xamarin driven • 手機最適合的Runtime　mobile-optimal Runtime ◦ minimal footprint, AOT, GC • C# compiler: 保持最新　keep up to date • 非同步函式庫　async class libraries
24. 發展方向 Development Direction MonoDevelop team • overall Windows / Mac improvements • core: project model, text editor ... ◦ NRefactory (C# CaaS) - with SharpDevelop • OSS addins: NuGet, PCL ... (Xamarin: product support addins)
25. 發展方向 Development Direction Community • Driven mostly by personal interests ◦ sometimes big project e.g. MonoGame • Xamarin based (mobile) community projects • Google Summer of Code (GSoC) - 2-3mo. projects
26. Running fun stuff on Mono
27. ASP.NET MVC5 最新的monodevelop支援MVC5。 "the latest monodevelop" supports MVC5. 利用NuGet軟體包 Makes use of NuGet packages
28. ASP.NET vNext • No IIS or System.Web.dll dependency • Can be distributed as one single app • highly modularized framework ◦ from servers to Mvc, SignalR, Identity...
29. ASP.NET vNext Running ASP.NET vNext on OSX and Linux setup "kvm" curl https://raw.githubusercontent.com/aspnet/Home/master/kvminstall.sh | sh source ~/.kre/kvm/kvm.sh kvm upgrade (use HelloWorldVNext c5c59b so far; master is broken) mono-aspnetvnext Docker image vNext is not quite ready to run complex apps right now...
30. Reactive Extensions (Rx) "Linq to Events" operate on events in Linq way filter, combine, transform events functionally another asynchronous programming approach Sample(), Window(), Merge(), ... hundreds Available on desktop and mobile (iOS/Android/WP)
31. F# Functional programming (non-pure) brings more type safety pattern matching, async, type providers still supports some imperative syntax MonoDevelop F# addin
32. Xwt + Rx public MyWindow () { this.Closed += delegate { Application.Exit (); }; var label = new Label (); var f = new Xwt.Frame () { WidthRequest = 200, HeightRequest = 200 }; var eo = Observable.FromEventPattern<MouseMovedEventArgs> (f, "MouseMoved") .Sample (TimeSpan.FromSeconds (1)); eo.Subscribe (v => label.Text = v.EventArgs.Position.ToString ()); var vb = new VBox (); vb.PackStart (f); vb.PackStart (label); Content = vb; } https://gist.github.com/atsushieno/b5c8beb54312f6452262
33. Xwt + Rx + F# type MyWindow () as this = inherit Window () do this.Closed.Add (fun ea -> Application.Exit ()) let label = new Label () let f = new Frame (WidthRequest = 200.0, HeightRequest = 200.0) let eo = Observable.FromEventPattern<MouseMovedEventArgs> (f, "MouseMoved") let sample = eo.Sample (TimeSpan.FromSeconds 1.0) sample.Subscribe (fun v -> label.Text <- v.EventArgs.Position.ToString ()) let vb = new VBox () vb.PackStart (f) vb.PackStart (label) this.Content <- vb https://gist.github.com/atsushieno/8f93bb13177677c78c9a
34. CppSharp C# and C++ interop using LLVM
