MongoDB failed to buid with /permissive- performance on MSVC. We use latest version of MongoDB to test VS copmlier. And we know building MongoDB with VS 2017 is currently not supported, so we apply patch to support this, I attach this patch. Could you please help to take a look at this? Thanks in advance!
