What are the best methods for visually designing a database using Entity Framework Core?

I find myself contemplating the best approach to designing my database scheme for optimal efficiency and visual appeal.

Currently, I am working on an ASP.NET Core application with Angular 2, utilizing Entity Framework Core (

"Microsoft.EntityFrameworkCore": "1.0.0"
) as my ORM. While I have a preference for SQL Server 2012, I am open to exploring alternative options such as PostgreSQL if they offer better database design capabilities.

Unfortunately, EntityFrameworkCore no longer supports the EDMX designer for creating the DataContext and its POCO classes.

Do you have any recommendations on how I can visually design my database and automate the generation of my POCO classes (and possibly my TypeScript classes)?

Can you suggest a tool for designing my database scheme that is more user-friendly than SQL Server Management Studio, similar to the EDMX designer that I used to like?

EDIT 2019-03-28

In light of the recent announcement in the SQL Server Management Studio changelog (18.0 Preview 7) deprecating Database Diagrams, I urgently need an alternative method to visualize my databases.

EDIT 2019-04-03

Since no one has provided a solution to my query yet, I thought it might be helpful for others to share this resource: VS Extension: Entity Developer ORM Designer for LINQ to SQL

EDIT 2019-07-15

According to the SSMS 19.1 Changelog:

Database diagrams have been reintroduced in SSMS.

Answer №1

If you choose to kickstart your project from the database, feel free to utilize any design tools that best suit your preferred database platform. Once you have designed your database, you can then utilize EF commands to generate your model and context from the database. By executing commands from the Package Manager Console, similar to how you would handle migrations in earlier EF versions:

Scaffold-DbContext "Server=yourServer;Database=yourDb;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

The comprehensive documentation delves into reverse engineering a model from a pre-existing database

Answer №2

If you're looking to easily scaffold a DbContext with entities, you can utilize the dotnet ef dbcontext scaffold command directly from the terminal or console. This allows you the flexibility to design your database in any way you prefer, and then with a simple scaffold command, you'll have your generated DbContext and corresponding classes ready to go.

For more information on this command, you can refer to the documentation available at:
