Which lib folder should I use for my portable library targeting net45, asp.net core 5.0 and windows 8?

Question

I am currently developing a portable library in C# that I want to publish on the NuGet official feed. I have published assemblies as NuGet packages before, but they were written against a single framework (.NET 4.0).

Now I'm confused how I should organize my lib folder in my NuGet package - my portable library can be used with .NET 4.5, ASP.NET Core 5.0, Windows 8, Windows Phone 8.1 and Windows Phone Silverlight 8 projects.

I tried to look up the framework profiles and their corresponding NuGet abbreviations, but I couldn't find them in the official documentation. Stephen Cleary gathered up profiles a while ago, but his list does not contain the profile for ASP.NET Core 5.0.

My actual question is: how should I structure the lib folder of my NuGet package? What is the profile name for portable libraries that target the framework versions mentioned above? And if I get that very profile name, is the assembly properly referenced in a non-portable library project (e.g. .NET 4.5 or WinRT)? Or should I make subfolders for the different framework version and copy the exact same assembly in all of them (which would largely increase the size of the package)? I habe seen some packages (like xunit.assert) doing it this way in NuGet Package Explorer.

The actual folder name that one has to use in this case is the following one:

portable-net45+wp80+win8+wpa81+dnxcore50
