KeyNotFoundException in DatabaseFirst

[pointlevel]

Hello!

I get a KeyNotFoundException "Key not found for TestProject.Setting" when trying to use the tracker.

Stacktrace:
vid TrackerEnabledDbContext.Common.Auditors.LogAuditor.GetPrimaryKeyValuesOf(DbEntityEntry dbEntry, List`1 properties)
vid TrackerEnabledDbContext.Common.Auditors.LogAuditor.CreateLogRecord(Object userName, EventType eventType, ITrackerContext context)
vid TrackerEnabledDbContext.Common.CoreTracker.AuditChanges(Object userName)
vid TrackerEnabledDbContext.TrackerContext.SaveChanges(Object userName)
vid TrackerEnabledDbContext.TrackerContext.SaveChanges()

My table has a primary key, and i have tried also with annotations, no difference. Tried to track other tables but with same result. Im using EF 6. Any ideas?

Show me your dbcontext code.

And its happening while saving a particular entity or all entities ?

Partial Public Class MyEntities
    Inherits TrackerContext

    Public Sub New()
        MyBase.New("name=MyEntities")
    End Sub

    Protected Overrides Sub OnModelCreating(modelBuilder As DbModelBuilder)
        Throw New UnintentionalCodeFirstException()
    End Sub

    Public Property Items() As DbSet(Of Item)
    Public Property Users() As DbSet(Of User)
    Public Property Logs() As DbSet(Of Log)
    Public Property Settings() As DbSet(Of Setting)

End Class

The exception occurs only when there is changes in the entity, but the same exception for all entities, yes.

This looks pretty normal... except for the fact that its auto generated.
Which is not usually the case in code first.

Are you using code first ?

Can u show me the code for above entities ?

Hello!

Im using DataBase first and the models are generated automatic from the DB. Is that a problem?

[bilal-fazlani]

This library works with code first only.

[bilal-fazlani]

I did some debugging to find out why its crashing with that exception and I found that its a bug in EntityFramework.MappingApi library.

https://efmappingapi.codeplex.com/workitem/1825

I have raised a bug there.

Great discover, hopefully they will fix it, or i have to change to Code First!
