Have a look at the <a href="https://github.com/aspnet/AspNetCore/blob/c565386a3ed135560bc2e9017aa54a950b4e35dd/src/Mvc/Mvc/src/MvcServiceCollectionExtensions.cs#L26" rel="nofollow noreferrer"><code>MvcServiceCollectionExtensions.cs</code></a> class on the <a href="https://github.com/aspnet/AspNetCore" rel="nofollow noreferrer">ASP.NET Core GitHub repo</a>:
<pre><code>public static IMvcBuilder AddMvc(this IServiceCollection services)
{
 if (services == null)
 {
 throw new ArgumentNullException(nameof(services));
 }

 var builder = services.AddMvcCore();

 builder.AddApiExplorer();
 builder.AddAuthorization();

 AddDefaultFrameworkParts(builder.PartManager);

 // Order added affects options setup order

 // Default framework order
 builder.AddFormatterMappings();
 builder.AddViews();
 builder.AddRazorViewEngine();
 builder.AddRazorPages();
 builder.AddCacheTagHelper();

 // +1 order
 builder.AddDataAnnotations(); // +1 order

 builder.AddCors();

 return new MvcBuilder(builder.Services, builder.PartManager);
}
</code></pre>
<code>AddMvcCore()</code> and <code>AddMvc()</code> both return an <code>IMvcBuilder</code> that can be used to further configure the MVC services.
<code>AddMvcCore()</code>, as the name implies, only adds core components of the MVC pipeline, requiring you to add any other middleware (needed for your project) by yourself.
<code>AddMvc()</code> internally calls <code>AddMvcCore()</code> and adds other middleware such as the Razor view engine, Razor pages, CORS, etc.
For now, I would follow what your tutorial suggests and stick to <code>AddMvc()</code>.
<hr />
As of ASP.NET Core 3.0, there are additional methods that give fine-grained control over what portions of the MVC pipeline are available to your application, e.g.:
<ul>
<li><a href="https://docs.microsoft.com/en-us/dotnet/api/microsoft.extensions.dependencyinjection.mvcservicecollectionextensions.addcontrollers?view=aspnetcore-3.0#Microsoft_Extensions_DependencyInjection_MvcServiceCollectionExtensions_AddControllers_Microsoft_Extensions_DependencyInjection_IServiceCollection_" rel="nofollow noreferrer"><code>services.AddControllers()</code></a></li>
<li><a href="https://docs.microsoft.com/en-us/dotnet/api/microsoft.extensions.dependencyinjection.mvcservicecollectionextensions.addcontrollerswithviews?view=aspnetcore-3.0#Microsoft_Extensions_DependencyInjection_MvcServiceCollectionExtensions_AddControllersWithViews_Microsoft_Extensions_DependencyInjection_IServiceCollection_" rel="nofollow noreferrer"><code>services.AddControllersWithViews()</code></a></li>
</ul>
Refer to <a href="https://www.strathweb.com/2020/02/asp-net-core-mvc-3-x-addmvc-addmvccore-addcontrollers-and-other-bootstrapping-approaches/" rel="nofollow noreferrer">this article</a> and MSDN for more information about what they do and when to use them.

I am learning ASP.NET Core MVC from a book, the code snippet in question is as follows:

<pre><code>// CHAPTER 4 - ESSENTIAL C# FEATURES
namespace LanguageFeatures {

 public class Startup {

 public void ConfigureServices(IServiceCollection services) {
 services.AddMvc();
 }

 // etc.
</code></pre>

Because the book is about ASP.NET Core MVC rather than ASP.NET MVC, I think I have to use <code>AddMvcCore()</code> rather than <code>AddMvc()</code> as follows:

<pre><code>public void ConfigureServices(IServiceCollection services)
{
 services.AddMvcCore(); // as opposed to:
 //services.AddMvc();
}
</code></pre>

Is what I do here correct?

Should I use AddMvc or AddMvcCore for ASP.NET Core MVC development?
