Profile front-end to back-end for dotnet core webapi (not razor)

I wanted to see if there was any community guidance already on how to profile from a dotnet core mvc front-end to back-end for dotnet core webapi (not razor)?

Am I just supposed to put the profiler on the backend and it magically just shows up?

When I do that I don’t see anything carrying across. I’m missing where in the documentation it might give guidance on that.

I know once upon a time there was a way to connect WCF to front-end, wasn’t there?
