# Database First with Entity Framework Core
Simple example of Database-First approach using Entity Franework Core.
## Packages required
- `Microsoft.EntityFrameworkCore.Design`
- `Npgsql.EntityFrameworkCore.PostgreSQL`
- `Microsoft.EntityFrameworkCore.SqlServer`
## CLI commands
- `dotnet ef dbcontext scaffold "Data Source=DESKTOP-P87PH2B;Initial Catalog=CodeFirstEntityFramework;Integrated Security=true;" Microsoft.EntityFrameworkCore.SqlServer -o SqlServerScaffold`
- `dotnet ef dbcontext scaffold "Server=localhost;User Id=postgres;Password=postgres;Database=CodeFirstEntityFramework;" Npgsql.EntityFrameworkCore.PostgreSQL -o PostgreSqlScaffold`
## Use case
Consider the case when we have a connection string to some database we want to reverse engineer.
Consider the database [CodeFirstEntityFrameworkCore](https://github.com/kolosovpetro/CodeFirstEntityFrameworkCore)
We have following connection strings:
- `"Server=localhost;User Id=postgres;Password=postgres;Database=CodeFirstEntityFramework;"`
- `"Data Source=DESKTOP-P87PH2B;Initial Catalog=CodeFirstEntityFramework;Integrated Security=true;"`
Using the commands:
- PostgreSQL:
`dotnet ef dbcontext scaffold "Server=localhost;User Id=postgres;Password=postgres;Database=CodeFirstEntityFramework;" Npgsql.EntityFrameworkCore.PostgreSQL -o PostgreSqlScaffold`
- MS SQL Server:
`dotnet ef dbcontext scaffold "Data Source=DESKTOP-P87PH2B;Initial Catalog=CodeFirstEntityFramework;Integrated Security=true;" Microsoft.EntityFrameworkCore.SqlServer -o SqlServerScaffold`
