    <p>I had EF Code First CTP4 working fine, and I installed CTP5 today. Now, I get an exception when my database is repopulated.</p> <p>Here is my model:</p> <pre><code>public class Member { public Member() { DateCreated = DateTime.Now; DateUpdated = DateTime.Now; DateLastLogin = DateTime.Now; } [Key, DatabaseGenerated(DatabaseGenerationOption.Identity)] \\I have tried removing these annotations and the result is the same public int MemberId { get; set; } [Required,RegularExpression(".+\\@.+\\..+", ErrorMessage = "Please enter a valid email address")] public string Email { get; set; } [Required,StringLength(20,MinimumLength=2)] public string FirstName { get; set; } [Required, StringLength(20, MinimumLength = 2)] public string LastName { get; set; } [Required, StringLength(36, MinimumLength = 2)] public string City { get; set; } [Required, StringLength(20, MinimumLength = 2)] public string State { get; set; } [Required, StringLength(20, MinimumLength = 2)] public string Zip { get; set; } public double GeoLat { get; set; } public double GeoLong { get; set; } public string AccountStatus { get; set; } public DateTime DateCreated { get; private set; } public DateTime DateUpdated { get; set; } public DateTime DateLastLogin { get; set; } public virtual PublicProfile Profile { get; set; } } </code></pre> <p>Here is the code that is being called in Global.asax.cs</p> <pre><code>protected void Application_Start() { RegisterRoutes(RouteTable.Routes); DbDatabase.DefaultConnectionFactory = new SqlConnectionFactory("System.Data.SqlClient"); DbDatabase.SetInitializer&lt;MeetPplDB&gt;(new Initializer()); } public class Initializer : DropCreateDatabaseAlways&lt;MeetPplDB&gt; { protected override void Seed(MeetPplDB context) { var Members = new List&lt;Member&gt; { new Member { Email = "dave@dave.com", City = "San Francisco", AccountStatus = "Active", State = "CA", FirstName = "David", LastName = "Daverson", Zip = "94118", GeoLat = 37.735, GeoLong = -122.392 }, new Member { Email = "bob@bob.com", City = "Oakland", AccountStatus = "Active", State = "CA", FirstName = "Bob", LastName = "Boberson", Zip = "94601", GeoLat = 37.781, GeoLong = -122.216 }, new Member { Email = "jenny@jenny.com", City = "San Francisco", AccountStatus = "Active", State = "CA", FirstName = "Jenny", LastName = "Jennerson", Zip = "94123", GeoLat = 37.735, GeoLong = -122.392 } }; Members.ForEach(m =&gt; context.Members.Add(m)); context.SaveChanges(); } } </code></pre> <p>When it hits the SaveChanges on the context, I get this exception:</p> <blockquote> <p>Conflicting changes detected. This may happen when trying to insert multiple entities with the same key.</p> <p>Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.</p> <p>Exception Details: System.Data.UpdateException: Conflicting changes detected. This may happen when trying to insert multiple entities with the same key.</p> </blockquote> <p>Does anyone have any idea what has changed and why this does not work any more? What needs to change for this to work?</p>

    1. COI cannot see anything wrong with your code or replicate the problem. Sorry, good luck.

    2. COI'm following [this series](http://blogs.msdn.com/b/adonet/archive/2011/01/27/using-dbcontext-in-ef-feature-ctp5-part-1-introduction-and-model.aspx) on CTP5, and my initializer doesn't have any `SaveChanges` calls, but still correctly populates the database. Maybe something between CTP4 and CTP5 changed regarding where changes are saved for an initializer?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
