17 lectures 01:31:41

Welcome to the "ASP.NET Web API 2 Hands-On" course and thank you very much for signing up!

In this short introduction, you will see what you're going to learn in this course. Have fun!

Preview 01:50

When you want to create a Web Service with Web API 2, you may find yourself in two different situations. You either want to build a new Web Application from scratch and use Web API 2 with that application, or you already have build a Web Application and add Web API 2 afterwards. In this lecture, we cover the first situation.

Preview 02:20

In this lecture, you will learn how to add Web API 2 to an already built Web Application in Visual Studio.

Preview 05:13

Web API uses the Model-View-Controller pattern. In this lecture, you will learn what this pattern actually means, and you will create your first model class in C#.

Preview 03:26

The controller implements the actual logic to a corresponding model. You learn to build your first controller in this lecture.

Preview 05:17

We want to use our new web service within a simple website. So we're going to add a new HTML page and install JQuery through the NuGet Package Manager to prepare our web application for the first web service call.

HTML & JQuery

You will make your first GET HTTP Request with JQuery and Web API 2.

GET HTTP Request

What does actually happen when you're calling a RESTful web service and why does it work with Web API 2? You'll find the answer in this lecture.

Network & Routing

In the last lectures, we received all available objects from the service. Now we only want to get a certain one. Here you will learn to write the server part.

Get Contact by ID - Server Side

In this lecture we're going to write the client part to get a single object from the service. Instead of $.getJSON(), this time we'll go into a little more detail by using $.ajax().

Get Contact by ID - Client Side

The first POST HTTP Request. We will create an object with JavaScript and add this object to the object array on the server.


The last two of the four HTTP methods. We will change an object by using a PUT request and remove an object by using DELETE.


So far, we know how to make any kind of HTTP Request with Web API and JQuery. But we only get a particular object by using its ID. What about using another property, e.g. the name? We'll cover this task in this situation.

Get Contact by Name - Web API Routing & Action

Web API 2 delivers the so called Attribute Routing. This gives you more control over your API design. You're free to choose any URI for your routes, create a typical RESTful structure and don't have to rely on the routing tables of the first release of Web API anymore.

Attribute Routing

Attribute Routing is not only about defining custom URIs. In this lecture you will learn how to use prefixes and constraints with this new feature.

Route Prefixes & Constraints

You're ready to start creating web applications with Web API 2. Congratulations! The next step is to save your data persistently in a database. Entity Framework enables you to do this. In this lecture, you will learn the first steps of how to use Web API with Entity Framework and look for changes on your objects in the database.

Entity Framework Code First Migration
  • You should have a little experience in C#

.NET 5 is the future.

It will combine the old .NET framework with .NET Core and that's why it’s about time to update this course with the latest version of .NET.

You will learn the crucial stuff about web development with Web API and Entity Framework in .NET 5 in no time so that you're able to join new projects and companies who are craving for .NET developers like you very soon.

With the example application, we're going to build you will be able to create, read, update, and delete contacts. We will use people you might even know, like Peter Parker or Tony Stark.

The tools we’re going to use are the .NET SDK, of course, together with Visual Studio to write our code, Postman to make our REST calls and SQL Server Express for our database.

Everything is available for free! So you already have everything you need to start developing with .NET 5.

A few minutes into the course, you will already make your first Web API call.

After that you create your own model and controller to make use of the Model-View-Controller pattern and implement all CRUD operations, meaning create, read, update and delete with the corresponding HTTP methods GET, POST, PUT and DELETE.

Then you will make your data persistent with the help of the object-relational mapper Entity Framework and code-first migration.

With all that knowledge, you are ready to conquer any .NET 5 back end application.

What You Will Learn


  • Download & install the .NET 5 SDK, Visual Studio 2019 Community Edition & Postman

  • Create your first Web API call within the first minutes

  • Initialize a Git repository for your source control


  • The Model-View-Controller (MVC) pattern

  • Create models and controllers

  • Attribute routing (with parameters)

  • All CRUD operations (Create, Read, Update, Delete)

  • The HTTP request methods GET, POST, PUT & DELETE

Entity Framework

  • Object-Relational-Mapping

  • Code-First Migration

  • SQL Server Express

  • How to use a DataContext and a proper ConnectionString

  • All previous HTTP requests with Entity Framework  to save your data in a SQL Server database

Your Instructor

My name is Patrick and I will be your instructor in this course. I’m a web developer for over a decade now, I have worked for big corporations and small teams, as an employee and a contractor and I just love to see the way Microsoft is going with .NET and how important it gets day by day.

To this date, I was able to run seven courses on web development here on Udemy about NET Core, single-page applications, Angular, and DevOps with a total of almost 50.000 unique students and more than 4.000 reviews.

If you have any questions, feel free to connect.

And if you still have any doubts, you have a 30-day money-back guarantee, no questions asked.

So, I hope you’re ready for your new skills and your new projects! ;)

I’m looking forward to seeing you in the course!
