C# 8 and .NET Core 3 Projects Using Azure - Second Edition

By: Paul Michaels, Dirk Strauss, Jas Rademeyer

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.

Configuring the Cosmos DB instance

Now that the resource is created, we can treat this database instance as though it was MongoDB. To start with, we'll need to launch the Data Explorer:

From here, we can select the following option to create a new collection:

It's worth noting that Fixed (10 GB) is not the recommended value, and, in a production-grade application, you would very likely want to choose Unlimited. If you do so, then you will need to provide a partition key. I've left the throughput as the default 1000 Request Units per second (RU/s): this effectively allows you to pay for the performance that you need; the slower you go, the cheaper it is (and vice-versa)! Once created, you should be able to see your new collection:

The last thing to do is to navigate to the connection strings tab and copy...
