About .NET Core• .NET Core is a subset of the .NET Framework• Many .NET Framework components are not in .NET Core• .NET Core is completely modularized. Each component is
distributed via NuGet• Apps can be updated independently and do not rely on
major framework releases• Deployment package includes everything needed to run• .NET Core will run on Linux, Windows, and OSX
6
Two parts of .NET Core•Runtime/Libraries:• CLR, libraries, compilers, etc.•Won’t change before RTM
•Tooling:• Supports .NET Core and ASP.NET Core, including the new command line tools and bits that plug into Visual Studio & Visual Studio Code•Will change before RTM
7
DifferencesFeature .NET Framework .NET CoreLibrary Installation Centralised Distributed with each app
Updates One big update. You better get your app ready
Updates to framework are independent of app.
Update NuGet packages when you are ready
Platforms Windows is the only one for me
I love everyone! Windows, OSX, Linux
Base Class Library All the things! You get the entire BCL

Strange Times…
Visual Studio 2015 and ASP.NET Core: Support for npm, bower, gulp, grunt, etc.

ASP.NET Core
What about ASP.NET 5?
• ASP.NET Core 1.0 was previously called ASP.NET 5• It was renamed in January 2016• You may still see it referred to as ASP.NET 5 in
Visual Studio and in some docs• Was updated in latest ASP.NET Core Release

ASP.NET Core ~ What is it?• ASP.NET Core 1.0 is a console app• In RC1, an ASP.NET application was a class library that contained a
Startup.cs class• As of RC2, an ASP.NET Core application is a .NET Core Console
application that calls into ASP.NET specific libraries• So code that used to live in the ASP.NET Hosting libraries
and automatically runs your Startup.cs now lives inside a Program.cs
22
ASP.NET Core ~ The features•Hosting• Kestrel, Startup
•Middleware• Routing, authentication, static files, diagnostics, error handling, session, CORS, localization, custom
•Dependency Injection•Configuration• Logging• Identity
23
ASP.NET Core ~ Which editors & IDEs?•Visual Studio 2015 Update 2 including Community•Visual Studio Code with C# extension•An OmniSharp-enabled editor:• Atom • Emacs
• Brackets • Sublime Text• Yeoman • Vim
24
ASP.NET Core ~ What can you do?•ASP.NET•MVC Web Apps in C#•Web API apps• Console apps• .NET Core compatible class library
•Signal R and Web Pages are coming after RTM
MVC + Web API + Web Pages =
ASP.NET Core MVC
26
ASP.NET Core MVC•One set of concepts – remove duplication•Web UI and Web APIs•Built on ASP.NET Core•Supports .NET Core•Runs on IIS or self-hosted•Deep integration with DI
OWIN (Open Web Interface for .NET)• OWIN in an open, community owned specification• OWIN defines pluggable middleware and hosting• ASP.NET 4.5 and ASP.NET Core 1.0 both support OWIN
28
Deployment portability•Two main models:• Portable Apps• Self-contained Apps
29
Portable Apps•Default application type in .NET Core•Require .NET Core to be installed on the target machine•Your application is portable between installations of .NET Core•No need to decide upfront which OSes your app will run on
30
Self-contained Apps•All app dependencies, including the .NET Core runtime, is part of the application•The app is larger, but also capable of running on any .NET Core supported platforms with the correct native dependencies•Need to make an explicit choice which platforms your application needs to run on during dev
31
Setting Portability• Portable: • Self Contained:• Target .NET Core
libraries in project.json
• Remove any "type": "platform" properties
• Add a runtimes node in your project.json
• •
Tooling Changes
33
What’s new in ASP.NET Core RC2?• .NET CLI (SDK) and IDE updates•Tag Helpers• IIS support baked in•Host RC2 apps in Azure App Service•Docker support with a new version of Docker Tools for Visual Studio 2015
34
ASP.NET Core SDK•The .NET Core SDK includes enough software to build an app•The SDK gives you both the .NET Core Tools and a copy of .NET Core•https://www.microsoft.com/net/core#windows
DemoASP.NET Core 1.0 from the SDK
36
ASP.NET Core IDE•The best way to develop with .NET Core on Windows is to download the Visual Studio official MSI Installer and the latest NuGet Manager extension for Visual Studio•https://www.microsoft.com/net/core#windows
DemoASP.NET Core 1.0 from the IDE
TagHelpers: Evolution of HTML Forms
•HTML helpers expressed as tagsEx. Instead of: @Html.LabelFor(m => m.UserName, new { @class = "col-md-2 control-label" })Write this: <label asp-for="UserName" class="col-md-2 control-label"></label>
• Easier to customize with more attributes•Work seamlessly with the HTML editor•Markup now looks like HTML and it comes with full IntelliSense

41
What about Entity Framework?•EF6.x most current and runs on .NET Framework 4.6•Entity Framework 7 renamed to Entity Framework Core 1.0•EF Core is a new code base that does not inherit all the features and API surface of EF6.x•EF6.x will continue to be a supported for some time
42
When to use EF Core?•EF6.x will still be the most suitable choice for most applications•EF Core recommended for:•New applications that do not need features that are not yet implemented in EF Core• Applications that target .NET Core, such as Universal Windows Platform (UWP) and ASP.NET Core apps
Web APIs
In ASP.NET 4.6 – Separate Stack
ASP.NET Core
Web API
JSON XML
Web Forms
HTML
MVCWeb Pages
In ASP.NET Core:API services are an ASP.NET Core feature
Microsoft /web
®
Sample Read-only Model and Controllerpublic class Person{ public int Id { get; set; } public string Name { get; set; }}
Step 1:Create a Model
[Route("api/[controller]")]public class PersonController : Controller{ List<Person> people; public PersonController() { this.people = new List<Person>(); this.people.AddRange(new Person[] { new Person { Id = 1, Name = "Chuck Norris" }, new Person { Id = 2, Name = "David Carradine" }, new Person { Id = 3, Name = "Bruce Lee" } }); }}
Step 2:Make an API Controller
Microsoft /web
®
Read-only Controller Actions to return data// GET /api/person[HttpGet]public IEnumerable<Person> Get(){ return this.people;}
Step 3:Return everything
// GET /api/person/5[HttpGet("{id}")]public Person Get(int id){ return this.people.FirstOrDefault(x => x.Id == id);}
Step 4:Return one item
Routing a Web APIapp.UseMvc(routes =>{ routes.MapRoute( name: "default", template: "{controller=Home}/{action=Index}/{id?}");});
Routing:Familiar syntax, conventional approach
[Route("api/[controller]")]public class PersonController : Controller {
[HttpGet("{id}")] public Person Get(int id) { /* ... */ }}
Attribute routing:Easy to configure
