This happen after Visual Studio Community 2017 latest update. Every time I try to open my project I get following warning:
Warning IDE0006 Error e
@Delfi - I updated VS 2017 on Friday 2017-08-18 and starting getting the same "ResolvePackageFileConflicts" build error today on some projects. I noticed the issue happening when any reference in the .csproj file has a Hintpath. After using Notepad to remove the Hintpath from affected references the builds work fine now.
This appears to be an issue with the latest VS 2017 update. Visual C# 2017 00369-60000-00001-AA019 Microsoft Visual C# 2017
Example:
..\..\..\..\..\Program Files\Atalasoft\DotImage 10.0\bin\4.0\Atalasoft.dotImage.WinControls.dll
False
Changed to...

False

Hope this helps you with your issue.
Note: I did not try it but this could also probably be fixed by removing and re-adding the affected references in the project through the solution explorer.
