I would but its not able to correlate the dependencies with requests unless i use the package Microsoft.ApplicationInsights.Web to set the correlation id. (I dont want to use Microsoft.ApplicationInsights.Web as it pulls in system.web).

For people dropping by and wondering about CallContext: Heres a small demo that shows how it works: https://gist.github.com/s093294/8a60759d9d29d2a33b8b

Yes, CallContext will not be saved across async/await. We are working on improving Dependency correlation to Requests and generic items correlation.
For RemoteDependencies - why wouldn't you just use
Microsoft.ApplicationInsights.Extensibility.RuntimeTelemetry.RemoteDependencyModule?
