error APPX0702: Payload file 'GameAssembly.dll' does not exist.

I'm trying to build (Solution=Release, Platform=x64) an UWP project (Unity 2018.1.0b8) in Visual Studio 2017 Community (15.3.4) and always get the following error:

Code (CSharp):

1. 2>C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\Microsoft\VisualStudio\v15.0\AppxPackage\Microsoft.AppXPackage.Targets(2264,5): error APPX0702: Payload file 'C:\Users\crash\Documents\Wolf_2018_1\Unity\build\Build_UWP_Profile_E01\build\bin\x64\Release\GameAssembly.dll' does not exist.
2. 2>Done building project "Wolf.vcxproj" -- FAILED.

VS is actually able to compile all .cpp files successfully, but it seems to fail while trying to link GameAssembly.dll. I was able to locate GameAssembly.lib in the output directory, but the dll file is missing.

Any idea what could cause this issue?

Here is the output of "Build Solution"

I deleted the "build" directory and triggered a "Rebuild All", which did the trick.
Thanks!
