Using: EF 4.3.1, Visual Studio 2010, SQL CE 4.0 My understanding is that when declaring Foreign Keys with DataAnnotation in EF, it can be done either of the following ways: Option 1- [ForeignKey("Player1Home")] public long? HPlayer1Id { get; set; } public virtual Player Player1Home { get; set; } Option 2- public long? HPlayer1Id { get; set; } [ForeignKey("HPlayer1Id")] public virtual Player Player1Home { get; set; } Problem: When the InverseProperty DataAnnotation gets used with Option 2 an extra column gets generated in the database (Player1Home_Id) in addition to HPlayer1Id. [Table("Matches"

I am trying to get identifiying relationships to work in Entity Framework so I can remove items from their collection using Remove. I have created a test like: public class OrderLine{ [Key, Column(Order = 0)] public int OrderLineId { get; set; } [Key, ForeignKey("Order"), Column(Order = 1)] public int OrderId{ get; set; } public virtual Order Order{ get; set; } [ForeignKey("Product")] public int ProductId { get; set; } public virtual Product Product { get; set; } public int Number { get; set; }} When I attempt to add a OrderLine like: var order=_orderRepository.Find(1); var NewOrderLine= new

I know how to do seed data with the migrations API in EF 4.3. I've been playing with that all night. However, my ultimate goal is to get my project to the point where a user can pull it from source control and press F5 and they are good to go, database, seed data, and all. Currently code-first does an excellent job of building the DB on a fresh build but seed data isn't inserted until I do Update-Database in the package manager console. At that point it runs the seed method and inserts my seed data. Is it okay to just do that in the OnModelCreating method? Can I still take advantage of the

I would like to fetch from database complex object using single query. Let's look at the following example: SELECT TableA.*, TableB.* FROM TableA INNER JOIN TableA.B_Id = TableB.Id and corresponding classes: public class QueryResult { public TableA A { get; set; } public TableB B { get; set; } } public class TableA { public int Id { get; set; } public string SomeContentA { get; set; } public int B_Id { get; set; } } public class TableB { public int Id { get; set; } public int SomeContentB { get; set; } } I would like to execute the raw SQL query from above against the database and get

I am using Entity Framework 4.3 Code First, and I have problem with updating many-to-many relationships. I defined the following classes: public abstract class Entity { [Column(Order = 0)] [Key] public int Id { get; set; } [Timestamp] [Column(Order = 1)] public byte[] Version { get; set; } } public class Video : Entity { public string Title { get; set; } public string Description { get; set; } public TimeSpan Length { get; set; } public virtual ICollection<Coworker> Coworkers { get; set; } } public class Coworker : Entity { public string FirstName { get; set; } public string LastName { get;
