WPF app using UWP libraries, "could not load file or assembly"

Question

i'm currently in the process of implementing BLE support in an existing WPF application. with there being no official support i decided to try and hack in the UWP API's. Im working in visual studio 2017.

when i create a new WPF application and use my class library everything is okay, however when i try to implement it in the existing application i get the following error for every uwp api called.

Problem generating manifest. Could not load file or assembly 'Path\to\project\bin\Debug\Windows.UI.Core.AnimationMetrics.AnimationMetricsContract.winmd' or one of its dependencies. An attempt was made to load a program with an incorrect format.

looking at other threads on stackoverflow i see that it might be an issue with clickonce publishing, where they added

<TargetPlatformVersion>8.0</TargetPlatformVersion>

to the class library .csproj file, but where do i add that? in the class library .csproj i only see the line

<TargetFrameworkVersion>v4.5</TargetFrameworkVersion>

anyone have an idea how i can get this to compile?

Did you check the x86/x64 bit option? – Jeroen van Langen May 30 '17 at 09:53 — Jeroen van Langen, May 30 '17 at 09:53
yep, this happens in the x86, x64 and any configurations. – Ron May 30 '17 at 09:54 — Ron, May 30 '17 at 09:54

In the end i went trough all the projects and found one that was distributed with clickonce.

following https://stackoverflow.com/a/29826962/7097407 i Edited the .Csjproj file and changed

<GenerateManifests>true</GenerateManifests>

to

<GenerateManifests>false</GenerateManifests>

and lo and behold my project compiled
