You could set your default values in the constructor for the entity, e.g.

C#

public class MyEntity
{
    public MyEntity()
    {
        IsActive = "Maybe";
    }

    [StringLength(1)]
    [Column(TypeName = "char")]
    public string IsActive { get; set; }
}

I thought you were using Code First? If you're creating your model from an existing database, you'd be better off setting the default value in the database and refreshing your model.

If you're using Code First, the only place you can set a default value - that will be effective in all cases - is in the constructor.

You could go down the route of creating custom attributes, but in the end it'll only achieve the same thing as initializing the property from the constructor, so is a waste of time in my opinion.

Keeping it in the constructor makes future maintenance easier too as you can see all of the default values in one place.
