Web Development with Microsoft• ASP – Active Server Pages – 1996 – VBScript, Jscript• XSP ( because everything cool starts with X) – prototype, written in Java • ASP.NET – 2002• ASP.NET MVC – 2007• ASP.NET MVC 3 – 2011 – Razor introduced• ASP.NET 5 RC – November 2015

New stack• VS2015• ASP .NET 5 (ex-vNext)• MVC 6• .NET Core vs .NET Framework vs Mono• DNVM (.NET Version Manager)• DNX (.NET Execution Environment)• DNU (.NET Development Utilities)• Kestrel

.NET Core• Primary goal: provide a single, modular, cross-platform version of .NET that works the

same across all platforms (Linux, Mac, iOS, Android)• Consists of:

• CoreFX (libraries)• CoreCLR (Microsoft.CoreCLR)

• Distributed via NuGet• Portable

DNX (.NET Execution Environment)• New project.json• Can cross-compile for both .NET Framework and .NET Core

• Recommendation from ASP.NET team: target both frameworks

DNX

Hosting model• dnu build & dnu pack & dnu publish• It’s possible to publish on Docker host (Azure or custom)• Kestrel Web server (https://github.com/aspnet/KestrelHttpServer/), based on libuv• IIS

• Helios up to beta7 (Microsoft.AspNet.Server.IIS) – uses existing System.Web• Kestrel from beta8 through IIS HTTP Platform Handler (https://

HTTP Platform Handler

Benefits/Consequences of Kestrel• IIS 7.5 at least (Win7)• Eases development for Microsoft• IIS AppPool does not need to run any managed code• No need in Windows Server• Existing modules still can run in IIS alongside the HttpPlatformHandler• No web.config (only app.config)• Unified servicing and boot-up• Integration with existing modules might be HARD

Client-Side Development• Gulp, Grunt support• Bower, npm support• Yeoman templates

RIP• No more Web Forms• HttpHandler-related features: e.g. Bundles• MVC – WebAPI separation • NuGet install.ps1/uninstall.ps1/content https://github.com/NuGet/Home/issues/627 • System.Web.HttpContext and so on

Startup• Startup class – entry point
