软件包与netcoreapp2.2不兼容

Question

I have ported one of my libraries to net core. It works fine from a netcore 2.2 web app. Now I want to package it with nuget. I use the folder convention way.

I have tried

lib/netcore/mylib.dll

lib/netstandard2.0/mylib.dll

lib/netcoreapp2.2

But I only get

What am I doing wrong? Thanks

edit: Nuget explorer seems to look allright? Whats going on? :/ Why is it saying netcore version 0.0?

edit: nuspec

If anyone else runs into this. Nuget keeps a cache. So even if you use a temporary local nuget folder for testing, it will use the cache, so if the cached one contains error (in my case a lib/netcore) it will not update.

Fixed by clearing cache
