Subject etc. should implement virtual Dispose pattern

[OpenEnergyGroup]

Hi, the Dispose pattern of Subject does not implement

protected virtual void Dispose(bool disposing){
...
}

it's instead

   public void Dispose(bool callOnCompleted)

which makes it impossible to inherit from Subject with a class that needs to call its own Dispose before the base. The canonical Microsoft solution examples are here .

Thank you!

Subject is not designed to be inherited, if it is misleading as such, it should be sealed.
