A type has a disposable field (a field that implements
IDisposable). This field
is being assigned on the type construction by constructing a new object. It is very
likely that the enclosing type owns the object and should then dispose it,
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.
