Recommended Approach Correlation Query for All Registrars in ASP.NET vNext

ILogger

has a method BeginScope

that is for correlation I think. I put together a sample: https://github.com/tugberkugurlu/AspNetVNextSamples/blob/3d36cdb4c2072d333d0e2583894c5616875ad8ed/src/LoggingSample/Startup.cs

Correlation seems to work with the NLog implementation in my example. However, with my approach above, I have not been able to find a way to define scopes between logger types. I solved this by using only one logger inside my application.

What is the recommended way to correlate requests between registrars in ASP.NET vNext?
