Sequence contains no matching elements error

/*I've narrowed the following error to the QuoteDBContext, which, when added to the modelBuilder, causes the error. Without this class added to the modelBuilder, I get another error that says "EntityType 'Quote' has no key defined. Define the key for this EntityType."*/
