C# Class Westwind.MessageQueueing.QueueMessageManagerMongoDb

An implementation of a MongoDb based multi-access Queue that provides random acccess to requests so they can be retrived for long running tasks where both client and server can interact with each message for processing. This implementation uses purely MongoDb server data access to handle the queue which works well for low to high volume loads. Great for long running tasks or even light workflow scenarios.
