I had EF Code First CTP4 that worked great, and today I installed CTP5. Now I get an exception when my database is re-populated.
Here is my model:
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; }
}
Here is the code that is called in Global.asax.cs
protected void Application_Start()
{
RegisterRoutes(RouteTable.Routes);
DbDatabase.DefaultConnectionFactory = new SqlConnectionFactory("System.Data.SqlClient");
DbDatabase.SetInitializer<MeetPplDB>(new Initializer());
}
public class Initializer : DropCreateDatabaseAlways<MeetPplDB>
{
protected override void Seed(MeetPplDB context)
{
var Members = new List<Member>
{
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 => context.Members.Add(m));
context.SaveChanges();
}
}
When it hits SaveChanges in context, I get this exception:
Conflicting changes detected. This can happen when you try to insert multiple objects with the same key.
