In the  code first approach we should be to create the class for defining the attributes for the DBContext

So lets first create a class for defining attributes

public class Employee   
{  
    public Employee ()  
    {   
      
    }  
    public int EmployeeID { get; set; }  
    public string Name { get; set; }  
}     

After doing this, we will create a context class that will implement the attributes.

Database name and table name should be specified in this context class.

ublic class Context: DbContext   
 {  
     public Context(): base()  
     {  
   
     }  
     public DbSet<Employee> Employees { get; set; }  
 }     

For  consuming  this we need to create a separate application or we will create a class that will implement these methods

using (var ctx = new Context())  
{  
    Employee emp = new Employee() { name = "Himanshu" };  
    ctx.Employees.Add(emp);  
    ctx.SaveChanges();                  
}
