 Q:

COM+ Component hosted by Windows Service in C# to control an external device

I have a Windows Service written in C# that controls a device connected to the computer by RS232 (gathers data and allows to control the device). It's named DeviceService and it's working properly. Now other applications use it by WCF services.
But now I need to expose some of functionalities as COM+ Component, so applications in C++ can communicate with this windows service (and get real-time data from it).
(I know that there might be better ways to do this but that's the requirement that can't be changed. It must be via COM+).
The problem is: when I create such a component in the DeviceService and activate it on the client it sees no data. For instance: static variables in Windows Service (DeviceService) return null for the component that is defined in the same assembly. Like it was another instance / context.
What is the proper way to host a COM+ component inside a windows service? So they share the same context (static variables).

A:

The correct way to do this is to put the COM+ component in Component Services and mark it as Multi-Threaded. All instances will share the same static variables.

RxSwift Disposable property isDisposed always false or Disposable closure newer called to cancel worker task

I need have some worker task in my observable which I want to cancel when there are no any subscriptions to my observable. But even when my observable have no subscriptions and even I got onDisposed event. The worker task in my observable continue it's execution while it must not because it depends on isDisposed property of my disposable but it is always false.

$ I_1 $, $ I_2 $, $ I_3 $ can be deduced from the polar decomposition of the Cardano formulas:
