. NET Core R2

Objective

A few days ago, the. NET core released the. NET Core 1.0.1 R2 preview, before thinking about having time to try. NET Core. For various reasons, there is no preliminary examination. Just a few days ago to see. NET Core released a new version, decided to go to explore. So, immediately go to the official website to find relevant information, to prepare for a preliminary study.

Here's the beginning of today's content, with two sections: Installing and creating sample programs.

Installation

I am using the Windows 64-bit system, installed the Visual Studio, if not installed, please install first.

Download the installation file

Go to the. NET core website, go to download page 1, go to download page 2, download the required installation files.

Example

Examples are the console program and the ASP. NET Core Web program.

. NET Core Console programs

Open Visual Studio 2015, create a new project: file-New-project

In the left-hand template, select . NET core, and on the right, select Console Application (. NET Core).
Enter NetCoreR2.Sample.ConsoleApp a name and click on the "OK" button.
Ok,.net Core Console application creation is complete.

Open the Program.cs file, write the code, run it.

using System;using System.Collections.Generic;using System.Linq;using System.Threading.Tasks;namespace NetCoreR2.Sample.ConsoleApp{ public class Program { public static void Main(string[] args) { Console.WriteLine("Hello .NET Core 1.0.0 R2 Console App!"); Console.ReadLine(); } }}

ASP. NET Core Web project

Create a new ASP. NET Core Web project on the solution above: Add-New project

Select ASP. NET Core Web application, and click "OK" to create the project.

Select Web Application

Change the authentication to: Do not authenticate, and then OK.

After you create the project, wait for the Neget package to restore, and then press "F5" to debug the run. You can choose IIS or Windowshosting, which is the latter.

Next, write a controller yourself and display the information.

Create a Hellocontroller controller and add an action for Index :

Using System;Using System.Collections.Generic;Using System.Linq;using System.Threading.Tasks; using MICROSOFT.ASPNETCORE.MVC; //for more information on enabling MVC for empty projects, visit http://go.microsoft.com/fwli nk/? Linkid=397860namespace netcorer2.sample.webapp.controllers{ public class HelloController: Span class= "Hljs-title" >controller {//GET:/<controller>/ public iactionresult Index ( "MSG"] =  "Hello. NET Core 1.0.0 R2 ASP. NET Core MVC app! "; return View (); }} 

Create the corresponding view file and write the code:

@{    ViewData["Title"] = "Hello Index Page";}"Msg"].ToString()
