In the previous post we
saw on how to setup a basic Asp.Net core MVC project using Visual studio. In this
post we shall examine the various files and methods in the basic project. As a
recap we used the following steps to create the basic MVC project.
public class Program
The full Startup class looks like this.
public class Startup
o Open
Visual studio (I am using VS 2017) and select new Project.
o Select
Web -> .Net Core
o Select
Asp.Net Core web application
o Provide
a name (Hello MVC) and path and click OK
o In
the templates select Web Application
(Model-View-Controller) and click OK
o This
will create a basic MVC project with one Controller and View
Now let us examine the
files and methods in the project. Let us start with the Program.cs.
This file looks similar to the basic Asp.Net Core project file. It hooks up the host and starts up the application.

public class Program
{
public static void Main(string[] args)
{
CreateWebHostBuilder(args).Build().Run();
}
public static IWebHostBuilder
CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>();
}
Next, let us look at Startup.cs
In the Startup there are 2 main things to look out for, first we add the Mvc service in the Configure method.
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
Next we add the useMvc middleware and MVC route definitions in the Configure() method.
app.UseMvc(routes =>

app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});

public class Startup
{
public
Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration
Configuration { get; }
public void
ConfigureServices(IServiceCollection services)
{
services.Configure<CookiePolicyOptions>(options
=>
{
options.CheckConsentNeeded =
context => true;
options.MinimumSameSitePolicy =
SameSiteMode.None;
});
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
}
public void
Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
}
app.UseStaticFiles();
app.UseCookiePolicy();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
}
}
}
Build and run the
application, it will load the Index view in the Home controller, which is the
default route for the MVC application.
