1>LINK : fatal error LNK1256: ALINK operation failed (80040436) : Error signing assembly -- Unknown error (8013141c) 1>Done building project "CLRCppLib.vcxproj" -- FAILED. ========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========

in VS2019

with project property

I've tried Framework version 4.8, 4.7.2 as well as 4.6 ; also values mykey.snk and $(projectdir)mykey.snk and "$(projectdir)mykey.snk"

but none seems working. Updated: while same project in VS2015 building fine in other system. there also no Container value is given.
