How to Create Asp.Net MVC Core 2.0 Application

In this article we will learn, what ASP.NET Core, its type and how to create ASP.NET Core 2.0 application with .net.

Question : What is Asp.Net Core 2.0 ?

Answer : ASP.NET Core 2.0 is the new web framework from Microsoft. ASP.NET Core 2.0 is the framework you want to use for web development with .NET.

Be keep in mind that .Net Framework and .Net Core Framework both are different to each other.

Question : what is difference between .Net Framework & .Net Core framework ?

Answer : There are many difference between both. Some are pointed below.

1. The current version of .NET Framework 4.7 while .NET core 2.0.

2. .Net Core is a cross platform that is you can use to develop application on Windows, Linux and MacOS while .Net Framework you can develop application on Windows only.

3. .Net Framework and .Net Core are two complete separate Frameworks.

Create ASP.NET MVC Core 2.0 Application step by Step.

Open Visual Studio go to File -> New->name with "Asp.NetMVCCore2.0Application"

Click on OK button, then below dialog box will appear.

Above screen shot Point 1 show which version of ASP.NET Core I am using, now option 2 shows select empty template and then click on OK button.

Now our application is created successfully. You can see the below snapshot.

Now close this tab.

Now you can see our Solution Explorer and it contains very less files.

As you can see above snapshot there are two files program.cs and Startup.cs. See the program.cs code and then Startup.cs.

Program.cs:

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using System.Threading.Tasks;

using Microsoft.AspNetCore;

using Microsoft.AspNetCore.Hosting;

using Microsoft.Extensions.Configuration;

using Microsoft.Extensions.Logging;

namespace Asp.NetMVCCore2._0Application

{

public class Program

{

public static void Main(string[] args)

{

BuildWebHost(args).Run();

}

public static IWebHost BuildWebHost(string[] args) =>

WebHost.CreateDefaultBuilder(args)

.UseStartup<Startup>()

.Build();

}

Startup.cs:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Threading.Tasks;

using Microsoft.AspNetCore.Builder;

using Microsoft.AspNetCore.Hosting;

using Microsoft.AspNetCore.Http;

using Microsoft.Extensions.DependencyInjection;

namespace Asp.NetMVCCore2._0Application

{

public class Startup

{

// This method gets called by the runtime. Use this method to add services to the container.

// For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940

public void ConfigureServices(IServiceCollection services)

{

}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.

public void Configure(IApplicationBuilder app, IHostingEnvironment env)

{

if (env.IsDevelopment())

{

app.UseDeveloperExceptionPage();

}

app.Run(async (context) =>

{

await context.Response.WriteAsync("Hello World!");

});

}

If solution or projects successfully created then rebuild the solution because for update latest version. Now rebuild the application.

When start the rebuild our project and finished this update, output window show the message which is given below.

After rebuild successfully, Run this application and show the output.

You can implement MVC inside Asp.Net Core 2.0, for implement MVC we need to three folders respective Controllers, Models, Views. After created successfully.

Add a controller with name “Home” and you can see snpashots.

After click on controller button you can see here controller dialog box appeared like MVC Application but I am using it in ASP.NET MVC Core 2.0 Application.

Now click on MVC Cotnroller button and then our controller dialog box will appear and I created it with name “Home”.

Now you can see then code over here.

Program:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Threading.Tasks;

using Microsoft.AspNetCore.Mvc;

namespace Asp.NetMVCCore2._0Application.Controllers

{

public class HomeController : Controller

{

public IActionResult Index()

{

return View();

}

Now Add view of Index Action.

ViewData["Title"] = "Index";

}

<h2>This is my first Asp.Net MVC Core 2.0 Application. </h2>

Before implement MVC in this application you can see the code of Startup.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Threading.Tasks;

using Microsoft.AspNetCore.Builder;

using Microsoft.AspNetCore.Hosting;

using Microsoft.AspNetCore.Http;

using Microsoft.Extensions.DependencyInjection;

namespace Asp.NetMVCCore2._0Application

{

public class Startup

{

// This method gets called by the runtime. Use this method to add services to the container.

// For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940

public void ConfigureServices(IServiceCollection services)

{

}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.

public void Configure(IApplicationBuilder app, IHostingEnvironment env)

{

if (env.IsDevelopment())

{

app.UseDeveloperExceptionPage();

}

app.Run(async (context) =>

{

await context.Response.WriteAsync("Hello World!");

});

}

In the above code inside ConfigureServices Method there is no any method and Configure Method only two conditions are available. For implementing the MVC inside Asp.Net Core 2.0.We have to change some code in Startup class.
We have to need use services.AddMvc() method inside ConfigureServices and add useapp.UseMvc(routes=> { routes.MapRoute(name:"default",template: "{Controller=Home}/{Action=Index}/{id?}"); }); inside Configure method. Which you can see the below code snippet.
