In this blog post we are going to add the jQuery, and bootstrap libraries to our ASP.NET Core application.  Normally we will use NuGet to bring in these libraries but ASP.NET Core gives you the option to use bower.json file to configure the dependencies that you will need on the client-side using NPM in the backend.

Here are the steps to import the client-side dependencies into our project:

1. First let's add bower.json file of the "NorthwindCafe.Web" project, Right-click on the NorthwindCafe.Web project and add a file called bower.json in the project

2.  Open the bower.json file the markup should look like this

{
 "name": "asp.net",
 "private": true,
 "dependencies": {
 }
}

In ASP.NET MVC there is a default layout file that the application use when one exists.  If you look at the markup at the top of the "Index.cshtml" file you will see that there is a markup to specify the layout of the page in the code below.

@{
    Layout = null;
}

The code above tells ASP.NET MVC to not assign any layout to the page because it is being set to null. In this blog we will build on our existing NorthwindCafe.Web  project and add a default layout view to the project so that each page in the project will have a common layout.  This is similar what you would a master page for in web forms.

In this post we will go over the process of enabling ASP.NET MVC in our application.  Just like static files, in order for us to use MVC in our application we have to tell ASP.NET Core to use Mvc in the Startup.cs file.  We will continue to use the application "NorthwindCafe" that we used in our previous blog.

Here are the steps to add MVC to your application:

1.  Open the Startup.cs file, then in "Configure" method type in the following to enable MVC

       
        // 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.UseStaticFiles();
            app.UseMvc();
        }

As I have mentioned before ASP.NET Core decouples the application from the infrastructure as much as possible.  Therefore, you have to tell it exactly what you want in your project.  In this blog post we are going to tell ASP.NET that we want to serve static html files in our application.

Here are the steps to serve static files in our ASP.NET Core application.

1.  Open the "NorthwindCafe.Web" project, then click on the "Startup.cs" file in the project.  You will see the following markup in the Configure method

        public void Configure(IApplicationBuilder app)
        {
            app.Run(async (context) =>
            {
                await context.Response.WriteAsync("Hello World!");
            });
        }

2.  Go into the Configure method, remove the existing code and type in the following code
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            app.UseDefaultFiles();
            app.UseStaticFiles();
        }

Technology has moved at a breakneck speed, after working with ASP.NET Core for a while, I realized that my ASP.NET MVC blog articles have become outdated.  Don't get me wrong, MVC is still a very big part of ASP.NET Core, but that's the thing it's just a part of it.  ASP.NET Core has decoupled the infrastructure from the application.  You can deploy your web app on Docker imagine that!  No longer is IIS your primary means of hosting your ASP.NET application.

However, with this new freedom comes added complexity.  No longer can you just drag and drop components into your design surface.  Those days are long gone.  This post ist meant to ease your way into ASP.NET Core.  I will using the release candidate version two of ASP.NET Core for this post and other subsequent posts.  I found out that I can't really follow my blog posts anymore to create the project with the latest version which is 2.1.  Don't use 2.2 for now because there's still not a lot of documentation on it.  So here is the updated version  I will be using Visual Studio 2017 for my development.  You can use the command line interface and notepad to develop your ASP.NET Core application.  But, I think that borders on insanity.
