Is there a way to get the original Entity itself from the ChangeTracker (rather than just the original values)? If the State is Modified , then I suppose I could do this: // Get the DbEntityEntry from the DbContext.ChangeTracker... // Store the current values var currentValues = entry.CurrentValues.Clone(); // Set to the original values entry.CurrentValues.SetValues(entry.OriginalValues.Clone()); // Now we have the original entity Foo entity = (Foo)entry.Entity; // Do something with it... // Restore the current values entry.CurrentValues.SetValues(currentValues); But this doesn't seem very

I know it's several similar posts out there, but I cannot find any with a solution to this issue. I want to add a (sort of) AudioLog when adding, changing or deleting entities (soft-delete) in Entity Framework 6. I've overridden the SaveChanges and because I only want to add log entries for EntityStates Added, Modified or Deleted, I fetch the list before I call SaveChanges the first time. The problem is, because I need to log what operation has been executed, I need to inspect the EntityState of the entities. But after SaveChanges is called, the EntityState is Unchanged for all entries. public

Once creating a ASP.NET MVC5 project (with target framework is .NET 4.5.1 and the authentication type is Individual User Account ), so what is the most elegant way to configure the project so that it keeps the user, claims, roles etc. in an Oracle 12c database? I mean, how can I keep the authorization/authentication data in Oracle without deforming the automatically-generated MVC5 project structure. I guess changing the <defaultConnection> tag is not enough and there should be another Oracle implementation to replace Microsoft.AspNet.Identity.EntityFramework . It would be very helpful to

After migrating to Entity Framework 6 I get an error when executing unit tests on the build server. I'm using the DropCreateDatabaseIfModelChanges initializer. When I change it to MigrateDatabaseToLatestVersion everything works, but I want to stick with the former initializer. The error I'm getting is: System.InvalidOperationException: System.InvalidOperationException: The model backing the 'AppContext' context has changed since the database was created.

Background first: I have a database-first EF6 model in Visual Studio 2015 (latest nuget 6.1.3 pointing to a local SQL Server 2014 SP1 Express database) on a Windows 10 Pro laptop. After I upgraded from Windows 8.1 and Visual Studio 2013. I also upgraded the model from EF5 about 6 months ago as well, but I don't think this is relevant, as I've also tried rebuilding from scratch. The model: set of about 100 tables, 50 views and 250 associations. The problem is every time I want to make changes to my model, any kind of click (left or right) on the .edmx diagram causes Visual Studio to become
