Jason Alls

Traditionally associated with developing Windows desktop applications and games, C# is now used in a wide variety of domains, such as web and cloud apps, and has become increasingly popular for mobile development. Despite its extensive coding features, professionals experience problems related to efficiency, scalability, and maintainability because of bad code. Clean Code in C# will help you identify these problems and solve them using coding best practices.The book starts with a comparison of good and bad code, helping you understand the importance of coding standards, principles, and methodologies. You’ll then get to grips with code reviews and their role in improving your code while ensuring that you adhere to industry-recognized coding standards. This C# book covers unit testing, delves into test-driven development, and addresses cross-cutting concerns. You’ll explore good programming practices for objects, data structures, exception handling, and other aspects of writing C# computer programs. Once you’ve studied API design and discovered tools for improving code quality, you’ll look at examples of bad code and understand which coding practices you should avoid.By the end of this clean code book, you’ll have the developed skills you need in order to apply industry-approved coding practices to write clean, readable, extendable, and maintainable C# code.

Creating Cross-Platform C# Applications with Uno Platform. Build apps with C# and XAML that run on Windows, macOS, iOS, Android, and WebAssembly

Matt Lacey , Marcel Alexander Wagner

Developers are increasingly being asked to build native applications that run on multiple operating systems and in the browser. In the past, this would have meant learning new technologies and making multiple copies of an application. But the Uno Platform allows you to use tools, languages, and APIs you already know from building Windows apps to develop apps that can also run on other platforms. This book will help you to create customer-facing as well as line-of-business apps that can be used on the device, browser, or operating system of your choice.This practical guide enables developers to put their C# and XAML knowledge to work by writing cross-platform apps using the Uno Platform. Packed with tips and practical examples, this book will help you to build applications for common scenarios. You'll begin by learning about the Uno Platform through step-by-step explanations of essential concepts, before moving on to creating cross-platform apps for different lines of business. Throughout this book, you'll work with examples that will teach you how to combine your existing knowledge to manage common development environments and implement frequently needed functionality.By the end of this Uno development book, you will have learned how to write your own cross-platform apps with the Uno Platform and use additional tools and libraries to speed up your app development process.

Czysty kod w C#. Techniki refaktoryzacji i najlepsze praktyki

Jason Alls

Język C# cechują dojrzałość, prostota i nowoczesność. Służy on do wielu celów: do tworzenia aplikacji sieciowych, aplikacji działających w chmurze, oprogramowania dla urządzeń mobilnych i internetu rzeczy. Choć pozwala na pisanie kodu bezpiecznego, przejrzystego, wydajnego i prostego w konserwacji, zdarzają się przypadki, gdy jest on tak fatalnej jakości, że uzyskanie właściwej skalowalności i wydajności oprogramowania staje się niemożliwe. W takim wypadku trzeba zidentyfikować i rozwiązać problemy występujące w kodzie. Nie jest to łatwe zadanie. Dzięki tej książce zrozumiesz znaczenie standardów kodowania, zasad i metodologii. Dowiesz się, czemu służą przeglądy kodu oraz jak przyczyniają się do jego poprawiania oraz zapewnienia zgodności z uznanymi standardami. Opisano tu także testy jednostkowe, zagadnienia związane z techniką TDD oraz rozwiązywaniem zadań przekrojowych. Zaprezentowano dobre praktyki programowania obiektów, struktur danych, obsługiwania wyjątków oraz innych aspektów pisania programów w języku C#. Poszczególne zagadnienia zilustrowano licznymi przykładami działającego kodu C# oraz wyczerpującymi wyjaśnieniami w postaci procedur krok po kroku. W książce między innymi: dobre praktyki pisania kodu w C# implementacja metodologii fail-pass-refactor dla kodu w C# wzorce projektowe i ich stosowanie rozpoznawanie kodu złej jakości zabezpieczanie interfejsów API i usługa Azure Key Vault wykorzystywanie narzędzi do profilowania i refaktoryzacji C#. Sekret sukcesu tkwi w czystym i najbardziej przejrzystym kodzie
