            <summary>
            This class fuses logic from ObserverBase, AnonymousObserver, and SafeObserver into one class. When an observer
            needs to be safeguarded, an instance of this type can be created by SafeObserver.Create when it detects its
            input is an AnonymousObserver, which is commonly used by end users when using the Subscribe extension methods
            that accept delegates for the On* handlers. By doing the fusion, we make the call stack depth shorter which
            helps debugging and some performance.

            This type can be passed to overloads of the various method that adapt a TPL task as an
            <see cref="T:System.IObservable`1"/>. It deals with two concerns that arise whenever this is done:
            the scheduler through which notifications are delivered, and the handling of exceptions
            that occur after all observers have unsubscribed.
            </para>
            <para>
            If the <see cref="P:System.Reactive.Concurrency.TaskObservationOptions.Scheduler"/> property is non-null, it will be used to deliver all
            notifications to observers, whether those notifications occur immediately (because the task
            had already finished by the time it was observed) or they happen later.
            </para>
            <para>
            The <see cref="P:System.Reactive.Concurrency.TaskObservationOptions.IgnoreExceptionsAfterUnsubscribe"/> property determines how to deal with tasks
            that fail after unsubscription (i.e., if an application calls <see cref="M:System.IObservable`1.Subscribe(System.IObserver{`0})"/>
            on an observable wrapping, then calls Dispose on the result before that task completes, and
            the task subsequently enters a faulted state). Overloads that don't take a <see cref="T:System.Reactive.Concurrency.TaskObservationOptions"/>
            argument do not observe the <see cref="P:System.Threading.Tasks.Task.Exception"/> in this case, with the result that
            the exception will then emerge from <see cref="E:System.Threading.Tasks.TaskScheduler.UnobservedTaskException"/>
            (which could terminate the process, depending on how the .NET application has been
            configured). This is consistent with how unobserved <see cref="T:System.Threading.Tasks.Task"/> failures are
            normally handled, but it is not consistent with how Rx handles post-unsubcription failures
            in general. For example, if the projection callback for Select is in progress at the moment
            an observer unsubscribes, and that callback then goes on to throw an exception, that
            exception is simply swallowed. (One could argue that it should instead be sent to some
            application-level unhandled exception handler, but the current behaviour has been in place
            for well over a decade, so it's not something we can change.) So there is an argument that
            post-unsubscribe failures in <see cref="T:System.IObservable`1"/>-wrapped tasks should be
            ignored in exactly the same way: the default behaviour for post-unsubscribe failures in
            tasks is inconsistent with the handling of all other post-unsubscribe failures. This has
            also been the case for over a decade, so that inconsistency of defaults cannot be changed,
            but the <see cref="P:System.Reactive.Concurrency.TaskObservationOptions.IgnoreExceptionsAfterUnsubscribe"/> property enables applications to
            ask for task-originated post-unsubscribe exceptions to be ignored in the same way as
            non-task-originated post-unsubscribe exceptions are. (Where possible, applications should
            avoid getting into situations where they throw exceptions in scenarios where nothing is
            able to observe them is. This setting is a last resort for situations in which this is
            truly unavoidable.)

            Value-type representation.

            <remarks>
            <para>
            The public API surface area for <see cref="T:System.Reactive.Concurrency.TaskObservationOptions"/> is a class because
            using a value type would run into various issues. The type might appear in expression
            trees due to use of <see cref="T:System.Reactive.Linq.IQbservable`1"/>, which limits us
            to a fairly old subset of C#. It means we can't use the <c>in</c> modifier on
            parameters, which in turn prevents us from passing options by reference, increasing the
            overhead of each method call. Also, options types such as this aren't normally value
            types, so it would be a curious design choice.
            </para>
            <para>
            The downside of using a class is that it entails an extra allocation. Since the feature
            for which this is designed (the ability to swallow unhandled exceptions thrown by tasks
            after unsubscription) is one we don't expect most applications to use, that shouldn't
            be a problem. However, to accommodate this feature, common code paths shared by various
            overloads need the information that a <see cref="T:System.Reactive.Concurrency.TaskObservationOptions"/> holds. The
            easy approach would be to construct an instance of this type in overloads that don't
            take one as an argument. But that would be impose an additional allocation on code that
            doesn't want this new feature.
            </para>
            <para>
            So although we can't use a value type with <c>in</c> in public APIs dues to constraints
            on expression trees, we can do so internally. This type is a value-typed version of
            <see cref="T:System.Reactive.Concurrency.TaskObservationOptions"/> enabling us to share code paths without forcing
            new allocations on existing code.

            Groups the elements of an observable sequence according to a specified key selector function and comparer and selects the resulting elements by using a specified function.

            Determine whether a type represents a WinRT event registration token
            (https://learn.microsoft.com/en-us/uwp/api/windows.foundation.eventregistrationtoken).
            </summary>

            <returns>True if this represents a WinRT event registration token</returns>
            <remarks>
            <para>
            We used to perform a simple comparison with typeof(EventRegistrationToken), but the
            introduction of C#/WinRT has made this problematic. Before C#/WinRT, the .NET
            projection of WinRT's Windows.Foundation.EventRegistrationToken type was
            System.Runtime.InteropServices.WindowsRuntime.EventRegistrationToken. But that type is
            associated with the old WinRT interop mechanisms in which the CLR works directly with
            WinMD. That was how it worked up as far as .NET Core 3.1, and it's still how .NET
            Framework works, but this direct WinMD support was removed in .NET 5.0.
            </para>
            <para>
            If you're on .NET 5.0 or later, the System.Runtime.InteropServices.WindowsRuntime types
            are no longer supported. While you can still get access to them through the NuGet
            package of the same name (that's how .NET Standard 2.0 libraries are able to use these
            types) they are best avoided, because the types in that library are no longer the types
            you see when any of the WinRT types they are meant to represent are projected into the
            CLR's world.
            </para>
            <para>
            It was therefore necessary for Rx to stop using these types, and to drop its reference
            to the System.Runtime.InteropServices.WindowsRuntime package. We can replicate the
            same logic by looking for the type name. By checking for either the old or new
            namespaces, we can support both the old projection (still used on .NET Framework) and
            also the new C#/WinRT projection.

            This means two <see cref="T:System.Reactive.Notification`1"/> objects can be equal even though they don't represent the same observer method call, but have the same Kind and have equal parameters passed to the observer method.
            In case one wants to determine whether two <see cref="T:System.Reactive.Notification`1"/> objects represent the same observer method call, use Object.ReferenceEquals identity equality instead.

            This class implements a "task-like" type that can be used as the return type of an asynchronous
            method in C# 7.0 and beyond. For example:
            <code>
            async Observable&lt;int&gt; RxAsync()
            {
                var res = await Observable.Return(21).Delay(TimeSpan.FromSeconds(1));
                return res * 2;
            }
