'<classname1>' cannot inherit from <type> '<classname2>' because '<classname2>' is declared 'NotInheritable'
A class attempts to inherit from another class, but the desired base class is specified as NotInheritable. NotInheritable classes are used primarily to prevent unintended derivation.
Error ID: BC30299
To correct this error
- Remove the NotInheritable keyword from the definition of the desired base class, or remove the Inherits statement.
