P#

A framework for building, analyzing, systematically testing and debugging asynchronous reactive software. P# is used by engineers in Azure to design, implement and thoroughly test distributed systems and services.

Features

The P# framework provides:

  • Language extensions to C# for building event-driven asynchronous applications, writing test harnesses, and specifying safety and liveness properties.
  • A systematic testing engine that can capture and control all specified nondeterminism in the system, systematically explore the actual executable code to discover bugs, and report bug traces. A P# bug trace provides a global order of all communication events, and thus is easier to debug.
  • Support for replaying bug traces, and debugging them using the Visual Studio debugger.

Getting started
