I was working a bit ahead and planning for transition from EF 4.2 CTP to EF 5.0 and when "adding a code generation template" in VS11 + .NET 4.5 the DbContext template is no longer available. Any heads up on if one will be available and if not why (just curious)? Update: I see references to a DbContext template in the Enum tutorial, but yet I don't see the template in my VS11 project targeting .NET 4.5 with EF5.0 -pre installed. I see the other two V5.0 templates (EntityObject and Self-Tracking). Could it be a conflict with other installations, like in my case, Entity-Framework 4.2 CTP? I ran

I am trying to load a list of distinct colors from previously loaded list of products on a page. So to pull in the products I do this: var products = Products .Include(p => p.ProductColor) .ToList(); Then I do some processing on the products them I want to get a list of all of the distinct colors used by the products, so I do this: var colors = products .Select(p => p.ProductColor) .Distinct(); And this works great, however if I add a call to .AsNoTracking() to the original products call, I now get an entry in my color list for each entry in the product list. Why is there a difference in these

I've got this strange issue with Entity Framework 5 where I have a navigation property in one of my entities that I would like to set to null . But for some reason the property only gets cleared the second time I call this property: using (var db = new Entities()) { var vehicle = db.Vehicles.Single(v => v.Id == vehicleId); // After this call, ParkingBay is still set. vehicle.ParkingBay = null; // Only after this call, ParkingBay becomes null. vehicle.ParkingBay = null; db.SaveChanges(); } The Vehicle class that Entity Framework generates looks like this: public partial class Vehicle { public

So I have a UserProfile model class as part of SimpleMembership. In it I need to store a legacy identifier that exists in another DB of type char(36) . I'd love to change this to something more sensible like a uniqueIdentifier but that's out of scope for today's activities. My current annotation creates a column nvarchar(36) [StringLength(36)] public string UserIdentifier{ get; set; } I'd like a column of char(36) instead. Is this possible? If you want to keep with Data Annotations, then just simply use: [StringLength( 36 )] [Column( TypeName = "char" )] public string UserIdentifier{ get; set;
