 Internally, EF creates an entity type to represent the join table that will be referred to as the join entity type. There is no specific CLR type that can be used for this, so `Dictionary<string, object>` is used. More than one many-to-many relationships can exist in the model, therefore the join entity type must be given a unique name, in this case `PostTag`. The feature that allows this is called shared-type entity type.
