实体框架字符串为guid

Question

Hi my domain models use string as there Ids.

public class TeamModel
{
    public string TeamId { get; set; }
    public string TeamName { get; set; }
}

Where as my entities use a Guid as there Ids

     public class Team
     {
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public Guid TeamId { get; set; }
        public string TeamName { get; set; }
     }

Now im using automapper to map models to entities, just wondering if there is a data annotation that would allow me to set my TeamId as a string in the entity, but it then auto formats to a guid and generates the new guid before storing in the database

EDIT

The reason for string as Id in the domain model is because this is a research project with sql and mongoDb

my mongoDb entity looks like this

public class Team
{
    [BsonId]
    [BsonRepresentation(BsonType.ObjectId)]
    public string TeamId { get; set; }
    public string TeamName
}

So my domain will either pass a domain model to sql or mongo. Mongo converts string to ObjectId fine, I just need EF to be able to do something similar so I can use generic models in domain

Not I am aware of. Suggest (if you are really required to have it of string type in your model) to make additional properties that will convert to string\\guid in a set and get accessors .
