Type not found in context, possible mapping issue

c# entity-framework-6


I'm trying to use the EntityFramework.BulkInsert extension but I keep getting an exception of Type 'MyEntity.CallDetail' is not found in context 'MyEntity.MyEntities'. I tracked this exception to the DBMapping class in the EntityFramework.MappingAPI. The method that throws it is :

    public IEntityMap this[string typeFullName]
            if (!_tableMappings.ContainsKey(typeFullName))
                throw new Exception("Type '" + typeFullName + "' is not found in context '" + _contextTypeName + "'");

            return _tableMappings[typeFullName];

My question is, is this an error in the EntityFramework.MappingAPI or this this something in my code?

My context class:

public partial class MyEntities : DbContext
    public MyEntities()
        : base("name=MyEntities")

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
        throw new UnintentionalCodeFirstException();

    public virtual DbSet<CallDetail> CallDetail { get; set; }
    public virtual DbSet<PhoneState> PhoneStates { get; set; }
    public virtual DbSet<Skill> Skills { get; set; }
    public virtual DbSet<Team> Teams { get; set; }
    public virtual DbSet<User> Users { get; set; }
    public virtual DbSet<StateLog> StateLogs { get; set; }

I'm assuming that the error is caused by everything being DBSet<...> instead of just the type but I may be wrong.

If it is in my code (which is most probable) what do I need to do to make this work?

EDIT: Thanks to @BenRobinson, the issue is due to the EF mapping. I have been able to find that others have been having similar issues with EntityFramework.MappingAPI on DB first models as found here, here, and here. Since I am new to EF, I'm hoping that someone can see an issue in the edmx that could be causing the problem. Below is the info from the edmx file:

I was having this same issue, and was able to resolve it simply by updating my EntityFramework.MappingAPI ! NuGet MappingAPI . After updating, I simply rebuilt my project and no longer had the exception.

This exact error and proposed solution worked for me. After installation of the EntityFramework.BulkInsert-ef6 package, go back to Manage NuGet Packages and there should be an Update for EntityFramework.MappingAPI. After updating, run your context.BulkInsert(listOfObjects); line and it should succeed.
