Description

The operator == and operator != of Parameter does not check for null arguments. This means that the following construct throws an NullReferenceException:

if (store == null)
throw new ArgumentNullException("store");

Work around is to write the above as:

if ((object)store == null)
throw new ArgumentNullException("store");
