This book introduces ASP.NET Web Forms developers to Blazor in a way that is familiar and convenient. It introduces Blazor concepts in parallel with analogous concepts in ASP.NET Web Forms while also explaining new concepts that may be less familiar. It covers a broad range of topics and concerns including component authoring, routing, layout, configuration, and security. And while the content of this book is primarily for enabling new development, it also covers guidelines and strategies for migrating existing ASP.NET Web Forms to Blazor for when you want to modernize an existing app.
Who should use the book
This book is for ASP.NET Web Forms developers looking for an introduction to Blazor that relates to their existing knowledge and skills. This book can help with quickly getting started on a new Blazor-based project or to help chart a roadmap for modernizing an existing ASP.NET Web Forms application.
How to use the book
The first part of this book covers what Blazor is and compares it to web app development with ASP.NET Web Forms. The book then covers a variety of Blazor topics, chapter by chapter, and relates each Blazor concept to the corresponding concept in ASP.NET Web Forms, or explains fully any completely new concepts. The book also refers regularly to a complete sample app implemented in both ASP.NET Web Forms and Blazor to demonstrate Blazor features and to provide a case study for migrating from ASP.NET Web Forms to Blazor. You can find both implementations of the sample app (ASP.NET Web Forms and Blazor versions) on GitHub.
What this book doesn't cover
This book is an introduction to Blazor, not a comprehensive migration guide. While it does include guidance on how to approach migrating a project from ASP.NET Web Forms to Blazor, it does not attempt to cover every nuance and detail. For more general guidance on migrating from ASP.NET to ASP.NET Core, refer to the migration guidance in the ASP.NET Core documentation.
You can find the official Blazor home page and documentation at https://blazor.net.
