Cannot create a new account

INVALID_FIELD_FOR_INSERT_UPDATE

I receive this error when trying to create a new Account. I believe this error is occurring because the provider is attempting to set Person Account fields to NULL when this is not a Person Account record type.

Please specify the INSERT command you are using for adding the new record to the Account table.

I am using the Entity Framework and this is the error that I get when calling SaveChanges() after adding a new account.
