Using 0.1.2 my ~80 projects solution had ~10 of such warnings, using 0.1.3 I now have 185. Using VS 15.5.5

Thanks for the detailed repro @nnpcYvIVl!

Thanks @nphmuller and @slozier for up-voting the issue, and @stringy76 for giving a measure of the impact.

@pjanotti Can you please release hotfix to 0.1.3 alpha? Its a really critical issue that spam build output log very hard.
