EntityFramework.BulkInsert problems inserting into database

I am trying to use the EntityFramework.BulkInsert library to use EF6 and SqlBulkCopy.

The documentation seems to be very simple, however, I cannot get the data entered into the database.

For a complex example, here's the code:

public void WriteChunkNoAsync(int chunkCount, bool forceSave = false)
{
    Chunking.Entities.Add(this);
    if (forceSave || Chunking.Entities.Count % chunkCount == 0)
    {
        using (var db = new FlatESContainer())
        {
            //db.Entity.AddRange(Chunking.Entities); //This will work
            db.BulkInsert(Chunking.Entities);
            Chunking.Entities = new List<Entity>();
            db.SaveChanges();
        }
    }
}

      

        
        
        
      

    

This code will basically stick to the global list until the number of lists is divisible by chunckCount.

The AddRange function works fine. So, we decided to create a very simple database with one table "Test", and here is the problem we ran into:

List<Test> tests = new List<Test>();
for (int i = 0; i < 1000; i++)
{
    tests.Add(new Test());
}

using (var context = new SimpleContainer())
{
    //This works fine
    context.Tests.AddRange(tests);
    //This causes an exception: Type 'TestSimpleDatabase.Test' is not found in context 'TestSimpleDatabase.SimpleContainer'
    context.BulkInsert(tests);
    context.SaveChanges();
}

      

        
        
        
      

    

I believe these are separate issues, but perhaps someone from the stackoverflow community has an idea of ​​why we are having this problem.
