EntityFramework.BulkInsert issues inserting into database

I am attempting to use the EntityFramework.BulkInsert library for taking advantage of EF6 and SqlBulkCopy.

The documentation seems very straight forward, however, I cannot get any data populated into the database.

For a complex example, here is 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 insert into a global list until the list count is divisible by chunckCount.

The AddRange function works just fine. So, we decided to create a very simple database with a single table called "Test" and here is the issue 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 maybe someone in the stackoverflow community has any idea on why we are having this issue.
