How to implement DiagnosticSource & Activity in .NET core?

Question

I am looking for a sample which implements DiagnosticSource & Activity along with Hierarchical Request Id schema for HTTP correlation protocol

https://github.com/dotnet/corefx/blob/master/src/System.Diagnostics.DiagnosticSource/src/HierarchicalRequestId.md

I tried with few things but not able to log all incoming & outgoing requests on every scenario.

Please help on this.
