How can I debug validator failures in Visual Studio?

Developer VST 3 SDK
3

Thanks for the Info!

The issue is I cant find any information about the build failure at all in the log (even before the failure).

This is the full Output log copied from Visual Studio:

You can see I copied from the end of the last part of the build which reported [Succeeded]. Is there any information I’m missing here that could give me more info? It just seems odd to have a validator which doesn’t report the reasons it fails.

Thanks for your help!
