The context cannot be used while the model is being created

Question

In my application I receive the following error:

The context cannot be used while the model is being created.

I\'m not sure what

Answer 1

I had this error as well but was able to solve it by declaring a local variable context inside of each thread rather than using the one I had declared globally.

    Parallel.ForEach(myList, l=>
    {
        MyContext _db = new MyContext();
        // do some stuff....
        _db.Model.Add(....);
        _db.SaveChanges();

    });

Make sure you also set MultipleActiveResultSets=true in your connection string as described above.
