XML comment exception must have a 'cref' attribute
The <exception> tag provides a way to document the exceptions that may be thrown by a method. The required cref attribute designates the name of a member, which is checked by the documentation generator. If the member exists, it is translated to the canonical element name in the documentation file.

To correct this error
