I am using independent associations (with lazy loading) to access related entities in my code first model e.g. public class Aaa { public int AaaId {get;set;} public string SomeValue {get;set;} } public class Bbb { public int BbbId {get;set;} public string SomeValue {get;set;} public virtual Aaa MyIndependentAssociation {get;set;} } but I am wondering how to access the foreign key value of MyIndependentAssociation without actually loading the record. I am assuming the Aaa_AaaId value is actually loaded when I retrieve a Bbb entity from the database (according the debug visualizer on the entity

I'm using Entity Framework 5, Code-First. I've two domain objects (or tables). 1st is User , and 2nd is UserProfile . One user can have only one profile, and one profile belongs to only one user. That is 1-1 relationship. Here are the classes.... (I simplified the code to make it understandably, It is actually more complex) User public class User { public virtual Int64 UserId { get; set; } public virtual UserProfile UserProfile { get; set; } public virtual String Username{ get; set; } public virtual String Email { get; set; } public virtual String Password { get; set; } } UserProfile public

Code First has the attribute [NotMapped] for properties which are not to be mapped: how would one achieve the same thing in model-first mode? NotMapped properties are not part of your mapping. When the model first approach is used EDMX represents the mapping so every property defined in the diagram is mapped. If you want to have non-mapped property it must not be defined in the diagram. All classes generated by EF's code generation are partial so you only need to create your own partial part of the class (it must be in the same namespace and assembly as generated part) and define your non

I have been working with soft delete and now i want to load the navigation properties of my entity that are not "deleted". I have found a way, my problem this way is not to clear for me, there is another way to do this. Context.CreateSet().Include("Salary").Select(u => new {User= u, Salary = u.Salarys.Where(s => !s.Deleted)}).AsQueryable().Select(a => a.User).AsQueryable(); Eager loading doesn't support filtering. Your code can be simplified to: var users = Context.CreateSet<User>() .Select(u => new { User = u, Salary = u.Salaries.Where(s => !s.Deleted) }) .AsEnumerable() .Select(a => a.User);

I have an entity where the primary key consists of two foreign keys to two other tables. I have the configuration working with the following but the table is generated with two FK references. The table: domain.Entity1 MorePK (PK, FK, int, not null) Entity2_Id (PK, FK, int, not null) Entity3_Id (PK, FK, int, not null) OtherData (varchar, null) Entity2_Id1 (FK, int, null) Entity3_Id1 (FK, int, null) is generated from: public Entity1 { public int MorePK { get; set; } public int Entity2_Id { get; set; } public int Entity3_Id { get; set; } public string OtherData { get; set; } public virtual

I didn't find yet a good solution to this problem (similar ticket here EF5 update disconnected graph (n-tier) one-to-many ). I found and followed this example: http://entityframeworktutorial.net/update-many-to-many-entities-in-entity-framework.aspx#.UTBeTDBhif8 . This works just fine, but it creates a duplicate of the related entities (with sql profiler I saw the Insert into RelatedEntities .. I would expected just an insert / update on the MyEntities_Related join table and I don't understand why EF makes an insert on the RelatedEntities table :( And here is my code: public void AddOrUpdate

I am writing unit tests for my Generic Repository layer but i have some problems with DbEntityEntry . My Update method is like below. public virtual void Update(TEntity entityToUpdate) { var entity = dbSet.Find(context.Entry<ITrackedEntity>(entityToUpdate).Entity.Id); context.Entry(entity).CurrentValues.SetValues(entityToUpdate); } As you can see, context.Entry<TEntity>(TEntity entity) method is invoked by caller. So while unit tests this code throws null exception. I had tried to mock context.Entry method but i couldn't because i couldn't provide return value. My current test method is below

In a class library Ado.net Entity Data Model is has generated POCO classes. These were generated fine for the first time. But database changes are not being reflected. In edmx diagram right clicking and choosing Update Model from Database show newly created table but it do not add table even after selecting it to add. I tried running .tt (by right click and Run custom tool) but even it did not regenerated the Poco classes as per latest DB changes. Help please Not a fix but a workaround: Is it not an option to simply remove and regenerate the EDMX and the generated classes? That's what I do, it
