EF - Model First Approach Sample

Port EF6 EDMX to EFCore

In this approach, (EF Core) we model our entities and database context as code-based similar to Code-First. Then either using Migrations or DB Initializer, we create the database.

Language : C#
.Net Version : >=6.0

Pre-Requisites

Visual Studio IDE
Microsoft SQL Server
Azure Data Studio / SQL Server Management Studio (SSMS) / SSDT for Visual Studio

Scenario

Database with tables:
- Departments (Departments data like Name, IsActive)
- Employees (Employee data like Name, Email, Phone, DepartmentId, IsActive)
- Skills (Skills data like Name, IsActive)
- EmployeeSkills (Relation Mapping between Employee and Skill)
Each Employee belongs to a department and can have multiple skills.
