A type has a disposable field (a field that implements
IDisposable). This field
is being assigned on the type construction through a method call. It may be
possible that the enclosing type owns the object and should then dispose it as
IDisposible itself (if it does not yet implement yet).
A code fix will be presented to you that will transform the code, it will implement
IDisposable if the type has not implemented it yet, and add a call do
on the field.
