entity-framework-4.1

I'm trying to generate my entities from my SQL database using the ADO.NET Entity Data Model item and from there using the ADO.NET DbContext Generator. When I generate my edmx from the database one of my entities seems to be missing in the designer but when I look at the code behind of the edmx I see it in code and when I generate the dbContext the entity isn't generated at all... Any advice would be greatly appreciated! If the table you are missing an entity for is a join table for a many-to-many relationship you don't get an entity class when you create a model from the database. EF

I am trying to use a common EntityTypeConfiguration class to configure the primary key for all of my entities, so that each derived configuration class does not repeat itself. All of my entities implement a common interface IEntity (which says that each entity must have an Id property of type int). My configuration base class looks like this: public class EntityConfiguration<TEntity> : EntityTypeConfiguration<TEntity> where TEntity : class , IEntity { public EntityConfiguration() { HasKey( e => e.Id ); Property( e => e.Id ).HasDatabaseGeneratedOption( DatabaseGeneratedOption.Identity ); } }

weird one. (Probably not weird, at all) I have 3 objects, Employee, Rota and Department. public class Employee { public int Id { get; set; } public String Name { get; set; } public virtual Department Department { get; set; } } internal class EmployeeMapping : EntityTypeConfiguration<Employee> { public EmployeeMapping() { HasKey(a => a.Id); Property(a => a.Id).HasColumnName("UserId"); HasRequired<Department>(a => a.Department).WithOptional().Map(a => a.MapKey("DepartmentId")); } } public class Department { public int Id { get; set; } public String Name { get; set; } } internal class

I'm trying to use the mvc-mini-profiler with EFCodeFirst I'm creating a DbProfiledConnection and passing it to the DbContext on construction as below. The application continues to work as expected by the sql is not exposed to the Profiler. public class WebContext : DbContext { static DbConnection _connection = new SqlConnection(ConfigurationManager.ConnectionStrings["WebContext"].ConnectionString); static DbConnection _profiledConnection = MvcMiniProfiler.Data.ProfiledDbConnection.Get(_connection); public WebContext() : base(_profiledConnection, true) { } oops my bad. I've modified it so that

I'm using EF 4.1 to build a domain model. I have a Task class with a Validate(string userCode) method and in it I want to ensure the user code maps to a valid user in the database, so: public static bool Validate(string userCode) { IDbSet<User> users = db.Set<User>(); var results = from u in users where u.UserCode.Equals(userCode) select u; return results.FirstOrDefault() != null; } I can use Moq to mock IDbSet no problem. But ran into trouble with the Where call: User user = new User { UserCode = "abc" }; IList<User> list = new List<User> { user }; var users = new Mock<IDbSet<User>>(); users

UPDATE: After a bit more research it seems a number of my many-to-many mappings aren't working. Hmmm... I'm upgrading a data access project from EF 4.1 CTP4 to EF 4.1 RC and I'm having trouble with the new EntityTypeConfiguration<T> setup. Specifically I'm having an issue with a Many-to-Many relationship. I'm getting a Sequence contains no elements exception when I'm trying to get the .First() item. The particular exception isn't really that interesting. All it's saying is that there are no items BUT I know there should be items in the collection - so there must be an issue with my new

Relatively new to MVC and trying to get a cascading dropdown list working for train times. After looking at a lot of posts, people say that you should stay away from ViewBag/ViewData and instead focus on ViewModels, but I just can't seem to get my head round it, and it's driving me up the wall. Any tutorial seems to be either to complex or too easy and the whole viewModel idea just hasn't clicked with me yet. So here is my scenario: I have an admin system where staff can add individual train journeys. For each train time, I have an input form where the user can choose a Company, and from there
