Strange Build error after upgrading to Visual studio 2015 wants to copy pagefile.sys

Having VS 2015 14.0.25431.01 Update 3, without Xamarin, neither DotNetCompilerPlatform nuget package, and having more build configurations (eg. Debug and RCDebug), i get the unexpected copy which would be coming from another build (eg. copy corresponding to RCDebug but i Rebuild on Debug). It did not worked by deleting all the Bin folders, or Clean on every build config then Build. It builds fine BUT turns bad when Run.
