WinRT, Desktop world etc... - WinRT = Fixed set of API for Apps to reach into core Windows features/devices - Common runtime that connects to System Services with diverse views - APIs implemented in C++ .. lean performance - Part of OS - Supports your choice of UI & language - HTML5/JavaScript/CSS - XAML with C#, VB, C++ - Remember Fast & Fluid – any ops > 50ms (read most) = Await/Async - Win32 & .NET CLR all live - Metro IE10 = plug-in free - Regular IE supports Silverlight, Flash etc. - Fixed (careful) steps to migrate Windows Phone apps to Win8 Metro apps

- 14. Oh boy .. Asynchrony? - Not the same as Parallelism - Not necessarily multi-threading, but interweaving - APM Pattern: IAsyncResult result = BeginFoo(new AsyncCallBack(EndCallBackMethod), resultHandle); … private EndCallBackMethod (IAsyncResult result) { // EndFoo & stuff } - EAP Pattern: Foo.DownloadSomethingCompleted += ExecutionEndEventHandler(); Foo.DownloadSomething(); Private ExecutionEndEventHandler() { Dispatcher.BeginInvoked ( () => { // Grab results & Update UI. }); } - Hmmm … How bout this? No more callbacks! private async Method () { var results = await DoAsync (); // UI Binding. }
- 15. Opportunity .. Windows Re-Imagined!
