✦ Synopsis

Design, develop, and deploy a real-world web application by leveraging modern open source technologies. This book shows you how to use ASP.NET Core to build cross-platform web applications along with SignalR to enrich the application by enabling real-time communication between server and clients. You will use Docker to containerize your application, integrate with GitHub to package the application, and provide continuous deployment to Azure's IaaS platform.
Along the way,Real-Time Web Application Developmentcovers topics including designing a Materialize CSS theme, using a test-driven development approach with xUnit.net, and securing your application with the OAuth 2.0 protocol. To further your understanding of the technology, you will learn logging and exception handling; navigation using view components; and how to work with forms and validations. The rich code samples from this book can be used to retrofit or upgrade existing ASP.NET Core applications.

What You Will Learn

Design and develop a real-world web application


Implement security and data storage with OAuth2 and Azure Table Storage
Orchestrate real-time notifications through SignalR
Use GitHub and Travis CI for continuous integration of code
Master Docker containerization and continuous deployment with Docker Cloud to Azure Linux virtual machines


Who This Book Is For
Developers and software engineers interested in learning an end-to-end approach to application development using Microsoft technologies.
