@viktorklang sorry for the late response, the only other implementation in .Net I know of is Reactor but they haven't implemented the TCK

I'm low on time as I have to manage several projects so no promise on when Reactor.Core will do TCK. I merged in the environment support and have one test now that fails/hangs. It's kind of difficult to figure out why without the TCK sources at hand (which is neatly accessible in the JVM version).

Run the TCK on our concat() impl and these fail:
  • Required_spec109_subscribeThrowNPEOnNullSubscriber : we don't throw ArgumentNullException but rely on NullReferenceException implicitly
  • Required_spec309_requestNegativeNumberMustSignalIllegalArgumentException : I guess it is expected request() calls onError but generally that's a concurrency violation on onError if the request() is asynchronous relative to onError
  • Required_spec309_requestZeroMustSignalIllegalArgumentException : same as above

For now, I'll add a Tck() operator that behaves like the TCK expects...

FYI, the TCK now passes for the operator Concat:

@akarnokd RE: 3.09, the onError should be signalled as a response to requesting a negative number, i.e. it is not the request method itself that should do it, in the case of async publishers.

No problem, added a Tck() operator that serializes the call to OnError when called from request() with any other call to OnXXX.
