How to create index in Entity Framework 6.2 with code first

Question

Is there a way to create an index on a property/column using code-first, instead of using the new IndexAttribute ?

Answer 1

From EF 6.1 onward the attribute [Index] is supported.
Use [Index(IsUnique = true)] for unique index.
Here is the link from Microsoft

public class User 
{ 
    public int UserId { get; set; } 

    [Index(IsUnique = true)] 
    [StringLength(200)] 
    public string Username { get; set; } 

    public string DisplayName { get; set; } 
}
