Learn how to leverage the features of the new Entity Framework Core APIs and use them to build pure .NET Core applications. About This Book Learn how to effectively manage your database to make it more productive and maintainable. Write simplified queries using LINQ to acquire the desired data easily Raise the abstraction level from data to objects so teams can function independently, resulting in easily maintainable code Who This Book Is For This book is for .NET Core developers who would like to integrate EF Core in their application. Prior knowledge of .NET Core and C# is assumed. What You Will Learn Create databases and perform CRUD operations on them Understand and build relationships (related to entities, keys, and properties) Understand in-built, custom, and remote validation (both client and server side) You will learn to handle concurrency to build responsive applications You will handle transactions and multi-tenancy while also improving performance In Detail Being able to create and maintain data-oriented applications has become crucial in modern programming. This is why Microsoft came up with Entity Framework so architects can optimize storage requirements while also writing efficient and maintainable application code. This book is a comprehensive guide that will show how to utilize the power of the Entity Framework to build efficient .NET Core applications. It not only teaches all the fundamentals of Entity Framework Core but also demonstrates how to use it practically so you can implement it in your software development. The book is divided into three modules. The first module focuses on building entities and relationships. Here you will also learn about different mapping techniques, which will help you choose the one best suited to your application design. Once you have understood the fundamentals of the Entity Framework, you will move on to learn about validation and querying in the second module. It will also teach you how to execute raw SQL queries and extend the Entity Framework to leverage Query Objects using the Query Object Pattern. The final module of the book focuses on performance optimization and managing the security of your application. You will learn to implement failsafe mechanisms using concurrency tokens. The book also explores row-level security and multitenant databases in detail. By the end of the book, you will be proficient in implementing Entity Framework on your .NET Core applications.

So, you want to learn C# and Visual Studio 2022, but are a bit intimidated? Don't be. Programming is within your grasp! Programmers at any level have to fully understand, and more importantly, be able to code the core constructs. It is impossible to use complex programming concepts such as classes before understanding what methods and variables and their data types are. Once there is a foundation built on the basics, then all other topics can fall in line. While it is a forgone conclusion that languages change with the introduction of new features, the core concepts do not. Even large enterprises do not always update to the latest versions of languages and frameworks; their "backbone" applications have been developed to work, regardless. More than ever, enterprises need developers who can master and apply the core programming concepts and then be "up-skilled" with newer language levels and features as they integrate into the company. This book builds from the ground up. You will begin with an introduction to programming, learning the foundational concepts needed to become a C# programmer. You will then put to practice a wide range of programming concepts, including data types, selection, iteration, arrays, methods, classes and objects, serialization, file handling, and string handling. You will learn enough to develop applications that emulate commercial application code. Once you've got the foundational concepts, get ready to dive into common programming routines, including linear search, binary search, bubble sort and insertion sort, and use C# to code them. Code example annotations supplement the learning and are designed to enhance learning while also explaining why the code does what it does. This book: Teaches core programming through well-explained and simple-to-follow instructions Reinforces programming skills through the use of coding examples that extend user learnings Explains theoretical programming concepts; applies them practically with code examples Introduces the latest Microsoft C# Integrated Development Environment (Visual Studio 2022) Enlists clear, precise, and easy-to-understand language to assist readers of all levels and experience Uses a mix of "theory" and practical information that is designed to be friendly and engaging Who This Book Is For Beginners, those refreshing their C# skills, or those moving from another programming language. No skills or previous knowledge is required. Readers will need to download Visual Studio 2022 Community Edition as this is what the book code has been based on, but they could use other Integrated Development Environments.

Whether you are using Windows Forms to build rich-client business applications, or the ASP.NET 2.0 framework to build powerful web applications or web services, the use of well-designed graphics will greatly enhance their usability, impact, and visual appeal. This book provides a comprehensive guide to the use of graphics in .NET applications and aims to provide you with all the information you need to build effective custom controls. The opening section of the book investigates the .NET Framework classes that implement graphics. It covers all of the classes, methods, and techniques needed to create, manipulate, and display precise graphics in a form, a page being sent to a printer, or an image. On this foundation, the second section describes how to design and build effective custom controls for use in a business environment. Topics covered include building composite controls, implementing keyboard navigation, and enhancing design-time support. The final section of the book explores the use of GDI+ and ASP.NET to build custom controls that can provide reusable, GUI components for web projects, and to deliver customized graphics over the Internet.

With the release of .NET 2.0, the Visual Basic 2005 language has been updated with numerous new programming constructs (XML code documentation, operator overloading, generics, and partial types just to name a few!). Now more than ever, choosing a .NET language boils down to personal preference (rather than a languages feature set). However, to effectively make use of these language features, developers must have a rock-solid grounding in object-oriented technology, assemblies, and the core .NET technologies. The purpose of Pro VB 2005 and the .NET 2.0 Platform, Second Edition is to provide you with such a foundation by diving deep into the language of Visual Basic 2005 and the platform of .NET. Thus, rather than simply showing how a code wizard can generate all the code on your behalf, this text will first show you how to author the code yourself so you can alter the generated code to your liking. Beyond learning all the details of the VB 2005 programming language, you will also dive into the details of building desktop applications (using Windows Forms) and websites (via ASP.NET 2.0), and how to interact with relational databases (à la ADO.NET). Furthermore, you will explore how to build distributed applications using the .NET remoting layer and XML web services. Rest assured, this text will expose you to all the major services of the .NET platform and put you in the perfect position for further exploration.
