IDisposable Interface – finalizer provision in dervided classes in question

From [IDisposable Interface|Examples](https://docs.microsoft.com/en-us/dotnet/api/system.idisposable?view=net-5.0#examples)

```csharp
// Use C# destructor syntax for finalization code.
// This destructor will run only if the Dispose method
// does not get called.
// It gives your base class the opportunity to finalize.
// Do not provide destructors in types derived from this class.
```

From [IDisposable and the inheritance hierarchy](https://docs.microsoft.com/en-us/dotnet/api/system.idisposable?view=net-5.0#idisposable-and-the-inheritance-hierarchy)

> Subclasses should implement the disposable pattern as follows:
• They must override Dispose(Boolean) and call the base class Dispose(Boolean) implementation.
• They can provide a finalizer if needed. The finalizer must call Dispose(false).

Obviously these 2 statemens about finalizers (destructors) in derived classes are in contraposition.

----

Also this page does consistently uses either _finalizer_ or _destructor_ term. Correct term is [_finalizer_](https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/destructors). (Also last segment of link to Finalizers page uses _destructors_.)

> Finalizers (historically referred to as destructors) are used to perform any necessary final clean-up when a class instance is being collected by the garbage collector.
