I have created a small .NET Library (DLL) which does custom calculations and such.

I would like to create an Azure WCF service which basically wraps this libraries API.

The library, by necessity, is setup like an engine that must be initialized before use, so I don't want each and every service call to instantiate its own copy of the library. Is there a way to have the first call instantiate the library and then persist it somewhere so that other service calls will just use the same instance?

This sounds like you need to cache the objects outside of the service.

The recommended way for caching objects in Azure is using the Redis cache:
