Research on Scaffolding DbContext from Selected Tables in Entity Framework Core
This paper provides an in-depth exploration of how to perform reverse engineering from selected tables of an existing database to generate DbContext and model classes in Entity Framework Core. Traditional approaches often require reverse engineering the entire database, but by utilizing the -t parameter of the dotnet ef dbcontext scaffold command, developers can precisely specify which tables to include, thereby optimizing project structure and reducing unnecessary code generation. The article details implementation methods in both command-line and Package Manager Console environments, with practical code examples demonstrating how to configure connection strings, specify data providers, and select target tables. Additionally, it analyzes the technical advantages of this selective scaffolding approach, including improved code maintainability, reduced compilation time, and avoidance of complexity from irrelevant tables. By comparing with traditional Entity Framework implementations, this paper offers best practices for efficiently managing database models in Entity Framework Core.
