Modern Data Access with Entity Framework Core: Database Programming Techniques for .NET, .NET Core, UWP, and Xamarin with C# By 作者: Holger Schwichtenberg ISBN-10 书号: 1484235517 ISBN-13 书号: 9781484235515 Edition 版本: 1st ed. 出版日期: 2018-10-05 pages 页数: 665 Modern Data Access with Entity Framework Core: Database Programming Techniques for .NET, .NET Core, UWP, and Xamarin with C# C# developers, here’s your opportunity to learn the ins-and-outs of Entity Framework Core, Microsoft’s recently redesigned object-relational mapper. Benefit from hands-on learning that will teach you how to tackle frustrating database challenges, such as workarounds to missing features in Entity Framework Core, and learn how to optimize the performance of your applications, head-on! Modern Data Access with Entity Framework Core teaches best practices, guidance, and shortcuts that will significantly reduce the amount of resources you internally dedicate to programming data access code. The proven methods and tools taught in this book, such as how to get better performance, and the ability to select the platform of your choice, will save you valuable time and allow you to create seamless data access. Dive into succinct guidance that covers the gamut– from installing Entity Framework Core, reverse engineering, forward engineering (including schema migrations), and data reading and modification with LINQ, Dynamic LINQ, SQL, Stored Procedures, and Table Valued Functions- to using third-party products such as LINQPad, Entity Developer, Entity Framework Profiler, EFPlus, and AutoMapper. You’ll also appreciate excerpts of conceptual software architecture discussion around Entity Framework Core that might otherwise take years to learn. What You’ll Learn Understand the core concepts of Entity Framework Core, as well process models for existing databases (reverse engineering) and the generation of database schemas from object models (forward engineering) Study real-world case studies for hands-on EF Core instruction Get up to speed with valuable database access scenarios and code samples Discover workarounds to augment missing features in Entity Framework Core Use Entity Framework Core to write mobile apps Bonus online appendix covers Entity Framework Core 2.1 release updates Who This Book Is For Software developers who have basic experience with .NET and C#, as well as some understanding of relational databases.

C# Gridview行操作–行更新和行添加GridView可以以表格的形式显示数据源中的数据，应用的场合比较多，我现在对其使用情况做一个简单的整理，也许会写成一系列文章，先上第一篇：行更新和行添加行更新是用到GridView的事件OnRowEditing，OnRowUpdating，OnRowCancelingEdit，能更新的字段是在GridView的 TemplateField中添加有Ed

Visual Studio 是 C#开发人员的必备工具；正确理解它将提高您的生产力。在本章中，我们讨论了与 Visual Studio 相关的各种概念，包括其项目和模板，不同的编辑器和窗口，以及其调试功能。我们还研究了断点、调用堆栈跟踪和监视窗口，以及如何利用这些来优化调试过程。之后，我们探讨了 Git 和 GitHub 与 Visual Studio 的集成。最后，我们谈到了 Visual Studio 中可用的不同重构功能。在一本书的一章中很难涵盖与这样一个非凡的集成开发环境相关的所有概念；
