[UWP] Payload contains two or more files with the same destination path

Question

Hello,

I have a fairly simple app that I would like to publish. When I try to create an app package for x86, x64 and ARM, the process returns 163 errors which all say "Payload contains two or more files with the same destination path"

Here are a couple of examples:

Payload contains two or more files with the same destination path 'System.Runtime.dll', but they are different sizes. Source files: C:\Program Files (x86)\Microsoft SDKs\UWPNuGetPackages\runtime.win10-x86.microsoft.netcore.universalwindowsplatform\6.2.14\runtimes\win10-x86\lib\uap10.0.15138\System.Runtime.dllC:\Program Files (x86)\Microsoft SDKs\UWPNuGetPackages\runtime.win10-x86-aot.microsoft.netcore.universalwindowsplatform\6.2.14\runtimes\win10-x86-aot\lib\uap10.0.15138\System.Runtime.dll 

Payload contains two or more files with the same destination path 'System.Data.dll', but they have different content. Source files: C:\Program Files (x86)\Microsoft SDKs\UWPNuGetPackages\runtime.win10-x86.microsoft.netcore.universalwindowsplatform\6.2.14\runtimes\win10-x86\lib\uap10.0.15138\System.Data.dllC:\Program Files (x86)\Microsoft SDKs\UWPNuGetPackages\runtime.win10-x86-aot.microsoft.netcore.universalwindowsplatform\6.2.14\runtimes\win10-x86-aot\lib\uap10.0.15138\System.Data.dll 

Payload contains two or more files with the same destination path 'System.Threading.dll', but they are different sizes. Source files: C:\Program Files (x86)\Microsoft SDKs\UWPNuGetPackages\runtime.win10-x86.microsoft.netcore.universalwindowsplatform\6.2.14\runtimes\win10-x86\lib\uap10.0.15138\System.Threading.dllC:\Program Files (x86)\Microsoft SDKs\UWPNuGetPackages\runtime.win10-x86-aot.microsoft.netcore.universalwindowsplatform\6.2.14\runtimes\win10-x86-aot\lib\uap10.0.15138\System.Threading.dll

For the entire error list, see the PDF file: Error list when creating app bundles.pdf

How can I solve this issue? My Nuget packages are up to date.

I fixed this issue by selecting the newest target versions in all UWP library, they were not the same.
