Understanding an ASP.NET Core MVC website


Let's walk through the parts that make up a modern ASP.NET Core MVC application.

ASP.NET Core startup

Open the Startup.cs file.

Note that the ConfigureServices method adds support for MVC along with other frameworks and services such as ASP.NET Identity, as shown in the following code:

public void ConfigureServices(IServiceCollection services) 
{ 
   services.AddDbContext<ApplicationDbContext>(options => 
    options.UseSqlServer(Configuration 
    .GetConnectionString("DefaultConnection"))); 

   services.AddIdentity<ApplicationUser, IdentityRole>() 
    .AddEntityFrameworkStores<ApplicationDbContext>() 
    .AddDefaultTokenProviders(); 

   // Add application services. 
   services.AddTransient<IEmailSender, EmailSender>(); 

   services.AddMvc(); 
} 

Next, we have the Configure method, as shown in the following code:

public void Configure(IApplicationBuilder app, IHostingEnvironment env) 
{ 
   if (env.IsDevelopment())
