#Entity Framework Core

This roadmap outlines a structured learning path for ASP.NET Core developers, offering comprehensive guidance on topics including general development skills, C#, SQL basics, ASP.NET Core fundamentals, SOLID principles, ORM, dependency injection, databases, caching, logging frameworks, real-time communication, microservices, and testing. The guide is supplemented with resources, tutorials, and best practices to aid developers in advancing their skills and navigating the challenges within the ASP.NET Core ecosystem in 2024.

Explore a robust base class and repository designed to optimize Domain-Driven Design models via specifications, compatible with EF6 and EF Core. This solution streamlines data queries and abstraction within applications by minimizing repeated lambda expressions, thereby reducing potential bugs. It is effectively used in Microsoft’s eShopOnWeb reference application. The project highlights practical pattern implementations with ongoing updates like AsAsyncEnumerable and advanced evaluator extensions. Access detailed documentation and videos for deeper insights.

EFCore.Visualizer enables the visualization of Entity Framework Core query plans directly in Visual Studio, facilitating enhanced debugging. It supports multiple databases including SQL Server, PostgreSQL, and Oracle by displaying detailed query plans with metrics such as IO stats and predicates. This tool is compatible with EF Core 7 and above, and requires Visual Studio 17.9.0 or later, aiding in the efficient identification of potential query performance issues. During debugging sessions, SQL execution plans are easily visualized. Specific configurations such as Application Insights may need adjustments to ensure seamless usage, making this tool ideal for those looking to optimize EF Core queries.

The Architecture project showcases a forward-thinking approach using modern technologies and design principles, such as Clean Architecture and SOLID principles. It emphasizes structural clarity by avoiding cyclic dependencies and implementing separation of concerns. The use of technologies like .NET, ASP.NET Core, and Angular underpins the project's focus on simplicity and efficiency, including unit testing and single responsibility per request handling. This initiative serves as a valuable learning tool and reference point for new projects, reflecting key design patterns like Mediator and Result.

Entity Framework Core is an object-database mapper for .NET that supports LINQ queries, change tracking, updates, and schema migrations. It integrates with various databases like SQL Server, Azure SQL Database, SQLite, and others using its provider plugin API. With EF Core's flexible architecture, you can intuitively develop and manage your data models while benefiting from ongoing updates and community-driven enhancements. Whether you are building new applications or maintaining existing ones, EF Core offers essential tools for efficient data handling and migration.
