            <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.

            The <b>System.Reactive.Concurrency</b> namespace contains interfaces and classes that provide the scheduler infrastructure used by Reactive Extensions to construct and
            process event streams. Schedulers are used to parameterize the concurrency introduced by query operators, provide means to virtualize time, to process historical data,
            and to write unit tests for functionality built using Reactive Extensions constructs.

            <remarks>
            Specifying a TimeSpan.Zero value for <paramref name="timeSpan"/> is not recommended but supported, causing the scheduler to create buffers as fast as it can.
            Because all source sequence elements end up in one of the buffers, some buffers won't have a zero time span. This is a side-effect of the asynchrony introduced
            by the scheduler, where the action to close the current buffer and to create a new buffer may not execute immediately, despite the TimeSpan.Zero due time.

            The current <see cref="T:System.Threading.SynchronizationContext" /> is captured during the call to FromEventPattern, and is used to post add and remove handler invocations.
            This behavior ensures add and remove handler operations for thread-affine events are accessed from the same context, as required by some UI frameworks.
            </para>
            <para>
            If no SynchronizationContext is present at the point of calling FromEventPattern, add and remove handler invocations are made synchronously on the thread
            making the Subscribe or Dispose call, respectively.
            </para>
            <para>
            It's recommended to lift FromEventPattern calls outside event stream query expressions due to the free-threaded nature of Reactive Extensions. Doing so
            makes the captured SynchronizationContext predictable. This best practice also reduces clutter of bridging code inside queries, making the query expressions
            more concise and easier to understand.

            Converts a static .NET event, conforming to the standard .NET event pattern with a strongly typed sender and strongly typed event arguments, to an observable sequence.
            Each event invocation is surfaced through an OnNext message in the resulting sequence.
            Reflection is used to discover the event based on the specified type and the specified event name.
            For conversion of events that don't conform to the standard .NET event pattern, use any of the FromEvent overloads instead.

            If any subscription to the resulting sequence is disposed, the CancellationToken is set. The observer associated to the disposed
            subscription won't see the TaskCanceledException, but other observers will. You can protect against this using the Catch operator.
            Be careful when handing out the resulting sequence because of this behavior. The most common use is to have a single subscription
            to the resulting sequence, which controls the CancellationToken state. Alternatively, you can control subscription behavior using
            multicast operators.

            length. However, some windows won't have a zero time span. This is a side-effect of the asynchrony introduced by the scheduler, where the action to close the
            current window may not execute immediately, despite the TimeSpan.Zero due time.

            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 ITaskObservable&lt;int&gt; RxAsync()
            {
                var res = await Observable.Return(21).Delay(TimeSpan.FromSeconds(1));
                return res * 2;
