Overview of this book

.NET Core is a general-purpose, modular, cross-platform, and opensource implementation of .NET. The latest release of .NET Core 3 comes with improved performance and security features, along with support for desktop applications. .NET Core 3 is not only useful for new developers looking to start learning the framework, but also for legacy developers interested in migrating their apps. Updated with the latest features and enhancements, this updated second edition is a step-by-step, project-based guide. The book starts with a brief introduction to the key features of C# 8 and .NET Core 3. You'll learn to work with relational data using Entity Framework Core 3, before understanding how to use ASP.NET Core. As you progress, you’ll discover how you can use .NET Core to create cross-platform applications. Later, the book will show you how to upgrade your old WinForms apps to .NET Core 3. The concluding chapters will then help you use SignalR effectively to add real-time functionality to your applications, before demonstrating how to implement MongoDB in your apps. Finally, you'll delve into serverless computing and how to build microservices using Docker and Kubernetes. By the end of this book, you'll be proficient in developing applications using .NET Core 3.

Reading and writing data to MongoDB

In this section, we will have a look at how to read a list of work items from the MongoDB database and how to insert a new work item into the database (I use the term work item to refer to a task or a bug). This can be done by performing the following steps:

  1. In the Models folder, create a new class called WorkItem, as shown in the following screenshot:

public class WorkItem 
{ 
    public ObjectId Id { get; set; } 
    public string Title { get; set; } 
    public string Description { get; set; } 
    public int Severity { get...
