No results when profiling a build using the MSVC 2015 toolchain #22

What's the minimum MSVC toolchain this works with? I started data collection, ran a build which uses the compiler and linker from MSVC 2015, stopped data collection, and ended up with a 1K .scor file which when loaded seems to contain no data.

Does this have a minimum compiler version e.g. 2019 toolchains?

I just tested with the vs2019 toolchain in our build and it did generate data, so this seems to be confirmed on my end as likely.

That's right. The MSVC recorder is using the Microsoft C++ Build Insights SDK. As far I know this got introduced on MSVC version 16.1. Then on version 16.4 they added Template instancing data. I might be slightly wrong with the exact versions, but at least you can have a rough estimate.

My minor suggestion would be to put this in a minimum requirements section or notes section in the project readme. It's not a surprising thing in the end, but knowing it up-front would be nice :)
