Migrate your existing microservice cluster from ASP .NET to ASP .NET Core. While improved performance and cross-platform support are evident, this book helps you cut through the noise to determine how, when, and to what extent a migration is needed. Microsoft’s introduction of .NET Core has created a lot of excitement, but also a lot of confusion for developers accustomed to ASP applications and services. This book gives you specific steps to embark on a partial or full SaaS microservices system migration, factoring in limited resources, time, and finances. In addition to practical advice and real-world examples, many mishaps will be shared, providing you with a complete 360-degree view of a migration. As a developer intimately familiar with the migration process, author Iris Classon shares prescriptive guidance on every part of the system—from code, dependencies, editors, integration, and the deployment pipeline to a distribution model. You will come away with all the information you need to plan and prepare your migration to ASP.NET Core. What You’ll Learn Conduct an in-depth, pre-migration analysis of your system Know the differences between ASP .NET and ASP .NET Core Plan for and execute a full or partial migration to ASP .NET Core Understand the continuous integration and deployment process Gain insight on tools and templates that will accelerate and facilitate the migration process Leverage a real-world migration example, complete with genuine challenges Migrate specific components such as logging, authentication, data access, and more Who This Book Is For Developers who are considering or are tasked with migrating an existing microservice cluster from ASP.NET to ASP.NET Core. Experience with C#, Web API, ASP.NET, Visual Studio, and PowerShell is helpful.

This book predominately covers Microservices architecture with real-world example which can help professionals with ease of adoption of this technology. Following the trend of modularity in real world, the idea behind Microservice by Examples is to allow developers to build their applications from various independent components which can be easily changed, removed or upgraded. Also, it is relevant now because of enterprises are moving towards DevOps/ Modernization, this book will emphasize on containers and Dockers as well.

In 2016, Microsoft introduced the new generation of .NET called .NET Core. It brought many fundamental improvements to the platform, but there were also many breaking changes and missing APIs, especially when it comes to creating web applications. Upgrading any website running on .NET Framework to the new .NET Core proved to be a complex process, which can take months or even years. This book describes two approaches you can take to incrementally modernize legacy .NET web applications. It explains the changes that happened in ASP.NET MVC, ASP.NET Web API, Entity Framework, ASP.NET Identity, SignalR, and other libraries. It also shows a migration path for applications written in ASP.NET Web Forms: a technology which isn’t supported in the new .NET at all. In addition, the book describes the new frameworks available in the ASP.NET Core platform (Blazor, Razor Pages, ASP.NET Core MVC, SignalR Core, and so on) and helps you decide which technology will be the best fit. The book also covers several “soft” areas: how to explain the benefits or necessity for the modernization to your company management, how to deal with refactoring and improving the overall code quality during the entire process, and how to adjust the architecture of the application to be ready for another technology upgrade in the future. The topic of modernization is highly relevant. There are still plenty of legacy .NET applications that are being actively developed and maintained. Many of them were developed for 10+ years, they involve plethora of company-specific know-how, and it is not economically feasible to rewrite them from scratch. What You Will Learn Discover the changes you need to make in a legacy ASP.NET application to migrate it to .NET 8 and beyond Estimate the required effort and prepare the entire process Use the In-place or Side-by-side approach to modernize your application incrementally Migrate from ASP.NET Web Services or WCF to REST or gRPC Migrate from ASP.NET SignalR to SignalR Core or from Entity Framework to EF Core Migrate from Forms Authentication to ASP.NET Identity Migrate ASP.NET Web Forms to Blazor Server or DotVVM Migrate ASP.NET MVC and Web Pages to ASP.NET Core MVC and Razor Pages Refactor and clean up your codebase to make it more maintainable Who This Book Is For .NET developers who work with ASP.NET web applications running on the .NET framework, and tech leads and software architects who make technical decisions about legacy .NET projects used in their organization

This is the eBook of the printed book and may not include any media, website access codes, or print supplements that may come packaged with the bound book. Through four complete sprints, this book takes you through every step needed to build brand new cross-platform web apps with ASP.NET Core, and make them available on the Internet. You won't just master Microsoft's revolutionary open source ASP.NET Core technology: you'll learn how to integrate the immense power of MVC, Docker, Azure Web Apps, Visual Studio and Visual Studio Code, C#, JavaScript, TypeScript, and Entity Framework. Working through the authors' carefully designed sprints, you'll start with a blank canvas, move through software architecture and design, adjusting to user feedback, recovering from mistakes, builds, testing, deployment, maintenance, refactoring, and more. Along the way, you'll learn techniques for delivering state-of-the-art software to users more rapidly and repeatably than ever before.

You're a developer who knows nothing to Microservices. Which is fine, except that you need to start coding your next Microservices-based application using ASP.NET Core and Docker. Don't worry: I have you covered. I've been training hundreds of developers like you during 16 years, and converted my experience into this book. I know from experience teaching what takes more time to learn in Microservices, and will spend time only where appropriate. Plus this book is packed with exercises which build up into a full project: you develop two interdependent Microservices, each exposing a CRUD JSON API. You publish them in a Docker repository and run them in Docker. Read this book, and you can code your Microservices within a week.

Know the fundamentals of creating and deploying microservices using .NET 6 and gain insight from prescriptive guidance in this book on the when and why to incorporate them. The microservices architecture is a way of distributing process workloads to independent applications. This distribution allows for the independent applications to scale and evolve separately. It also enables developers to dismantle large applications into smaller, easier-to-maintain, scalable parts. While the return is valuable and the concept straightforward, applying it to an application is far more complicated. Where do you start? How do you find the optimal dividing point for your app, and strategically, how should your app be parceled out into separate services? Pro Microservices in .NET 6 will introduce you to all that and more. The authors get you started with an overview of microservices, .NET 6, event storming, and domain-driven design. You will use that foundational information to build a reference application throughout the book. From there, you will create your first microservice using .NET 6 that you can deploy into Docker and Azure Kubernetes Service. You will also learn about communication styles, decentralizing data, and testing microservices. Finally, you will learn about logging, metrics, tracing, and use that information for debugging. What You Will Learn Build a foundation of basic microservices architecture design Follow an example of using event storming and domain-driven design to understand the monolithic application modified for microservices Understand, via detailed commands, how Docker is used to containerize applications Get an overview of creating microservices from a monolithic application Call microservices using RPC and messaging communication styles with MassTransit Comprehend decentralizing data and handling distributed transactions Use Azure Kubernetes Service to host and scale your microservices Know the methods to make your microservices more robust Discover testing techniques for RPC and messaging communication styles Apply the applications you build for actual use Practice cross-cutting concerns such as logging, metrics, and tracing Who This Book Is For Developers and software architects. Readers should have basic familiarity with Visual Studio and experience with .NET, ASP.NET Core, and C#.
