I expected that the nuget.org repository would have the same versions that are released here in GitHub
I could not install Boostrap 4.4.0 via nuget because I could not install the popper.js 1.16.0 dependency via nuget
https://www.nuget.org/packages/popper.js/
Same issue, up!
In the meantime, ignore dependencies and manually setup popper:

Good suggestion and I wasn't aware of that option until you pointed it out! In this case I'm working on a team template in which we'd prefer to use the standard dependency settings and not have to configure custom bundles to work around the issue. Will await the new nuget packages before completing my new template, but good to know this is a possible work-around. Thanks!
FezVrasta are you no longer using NuGet to distribute Popper.js? Last updated 4/4/2018 Latest version: 1.14.3 is pretty far behind :O
nuget
Published! https://www.nuget.org/packages/popper.js/1.16.0
Just be careful, Popper v2 will not support NuGet or Bower, just npm and unpkg CDN.

Thanks for getting this updated so quickly. It's all working for me now and was able to complete my task.
