Tracing sequences

The most widely used diagnostic solution is application tracing; in a few words, it is the art of logging the application execution flow with emphasis on the event type and its description.

This is the same in reactive programming, thus, we have the ability to use specific sequences that mark messages with additional metadata or log out messages to analyze (or dump for further usages) the sequence flow in addition to the usual tracing tools available within the .NET world.

More than a simple reactive way of tracing, we can design specific diagnostic sequence flows with related filtering or manipulation, and the ability to use any other reactive operator to help us isolate interesting diagnostic information.

Materialize

The Materialize extension method produces a new sequence for diagnostic purposes that flows messages containing additional metadata information about the messages flowing in the sourcing sequence.

The great advantage of materializing a sequence is the ability...
