Could not find assembly 'System.Threading.ThreadPool, Version=4.0.10.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' referenced by 'Nito.AsyncEx.Interop.WaitHandles'.

I have an UWP App when I try to build it for ARM in Release configuration it can't find the System.Threading.ThreadPool assembly. Also the build takes forever before showing the output. (Over an hour, but not sure if this is actually part of the problem)

The project where this happens is https://github.com/LokiMidgard/WP10-Music-Player Actual Commit

I assume it'll work in x64. But I just started the build and if it takes as long as ARM I will comment on this thread when I'll be back from work.

Target Version is 1809 (Build 17763) Min Version is Creators Update (Build 15063) Library Version Nito.AsyncEx (5.0.0)

I think the only class I need is AsyncManualResetEvent
