Is there any way other than using Isolated Storage/DB to comunicate with AudioPlaybackAgents?

Question

Is there any way to comunicate directly with the AudioPlaybackAgent in windows phone 7 with out having to write a file to disk(Isolated Storage/DB).

Ideally I would want to expose a property or method that takes an object.

If no i would be happy with a string.

Answer 1

Due to the way that the agents are executed there's no way to call methods on the agent directly. Inter-process comms is not directly supported.

The only alternative to IsolatedStorage, for communication on the device, is to use a (SQL CE) database.
You could have both processes communicate via an external website but that's probably overkill and could cause issues if there was no network connection available.
