Start with Samples/V1.0Samples/LocalMediaSamples/PolicyRecordingBot/FrontEnd/Bot.cs at line 78 and trace initialization through Service.cs and WorkerRole.cs. Reproduce the mediaInitializationFailure during WorkerRole startup, then verify that certificate initialization completes without the private-key access exception.
