VS2017 performance profiling shows only function pointers in dotnet core application

I have a dotnet core project that runs through Kestrel.

I posted it and created both an exe that hosts the DLL and of course the dll.

When I use the Performance Profiler in VS2017, I set it to use instrumentation, I ensured that the csproj file properties are set to generate a "full" pdb (although I am starting to doubt it does anything that matters to the dotnet core, but the output the pdb file is larger than when it was configured for portability).

When all is said and done, I get the output of the profiler that looks like a linked image.

Is there a way with the current toolkit (4/5/2017) to get a useful output from the profiler?
