I have been binding in WPF application directly to the model classes (and skipping creating individual viewmodel classes). Now, after switching to EF6 and DBContext, I face an issue with the generated EF POCO classes since it looks its either kind of tricky or not even recommended trying to make INotifyPropertyChanged interface implemented directly to those classes. Currently: I don't want to go back to ObjectContext. I don't want to change T4 too much either. The suggestions on the web for changing T4 to achieve INotifyPropertyChanged looks too error-prone for me. Creating viewmodels for each

I'm using an embedded Firebird database with code first (Entity Framework 6). The first time the application runs, it works fine: the database gets created and the data gets inserted. But every time it runs after that, it throws the following exception: An exception of type 'System.NotSupportedException' occurred in FirebirdSql.Data.FirebirdClient.dll but was not handled in user code Additional information: Unknown data type The project includes the following NuGet packages: EntityFramework [6.0.2] Firebird ADO.NET Data provider (Entity Framework 6) [4.1.0.0] I added the DbProviderFactories

Let's make a case to explain my problem. MyTable1 +id +myTable2Id MyTable2 +id MyView1 +id +myTable2Id MyView1 exists in the case, from data from the MyTable1. Now i want to create a Navigation property from my EF6.1 Code first approach in my View to MyTable2. I know that it was possible from the database first approach, but is it also possible from the code-first approach and how? EDIT: I search some on internet, but due many meanings of the word View, it's very hard to find information on it. Also with the approaches in codes that i tried, i always get an error that the migration can't be

I have a many-to-many relationship between Agents and AgentGroups (psuedocode, abbreviated). public class Agent { public virtual List<AgentGroup> AgentGroups { get; set; } } public class AgentGroup { public virtual List<Agent> Agents { get; set; } } At some point in the code, I want to get all AgentGroups, and I want to prefetch/include the Agents for each group. I also want to pre-fill the AgentGroups collection on the Agents. This was working in EF 6 beta, but no longer works in EF 6 rc1: List<AgentGroup> allGroups = context.AgentGroups.Include("Agents").Include("Agents.AgentGroups").ToList(

I have Visual Studio 2012 and I'm using the Entity Framework stack with EF 6. I did all correct but while adding migration I am getting the error . System.Data.Entity.Core.ProviderIncompatibleException Here are the classes public class Order { public virtual int OrderID { get; set; } } The context file public ShoppingCartContext() : base("ShoppingCartDb") { Database.SetInitializer<ShoppingCartContext>(new DropCreateDatabaseAlways<ShoppingCartContext>()); } protected override void OnModelCreating(DbModelBuilder modelBuilder) { #region Entity Framework 6 RC-1 modelBuilder.Properties().Where(x =>

I am trying to use Entity Framework 6 with SQLite and running into a database locked issue when trying to use TransactionScope . Here is my code: using (var txn = new TransactionScope()) { using (var ctx = new CalibreContext()) { var book = ctx.Books.First(x => x.Id == 2); var author = ctx.Authors.First(x => x.Id == 3); book.Authors.Add(author); ctx.SaveChanges(); } txn.Complete(); } First line var book = ctx.Books.First(x => x.Id == 2); executes ok. but then once I move on to the next one I get an exception saying that my database is locked. Here is my app config: <configuration>

In EF6, I want to update/delete bulk data in one query. My code is using (var context = _dataContextFactory.GetContext()) { var result1 = from b in context.MyTables where new List<int> {592, 593, 594}.Contains(b.Id) select b; foreach (var item in result1 ) { item.StatusId = 3; } context.SaveChanges(); } But in Sql Profiler, there are three scripts exec sp_executesql N'UPDATE [dbo].[MyTable] SET [StatusId] = @0 WHERE ([Id] = @1) ',N'@0 int,@1 int',@0=1,@1=592 exec sp_executesql N'UPDATE [dbo].[MyTable] SET [StatusId] = @0 WHERE ([Id] = @1) ',N'@0 int,@1 int',@0=1,@1=593 exec sp_executesql N
