Why some nuget packages can not be used in net core?
Such as 'Def.1.1.1', which I successfully referenced but could not use.
The error is:
Compilation error (line 13, col 21): The name 'Def' does not exist in the current context.
The site shows that the package is "on disk", but '/usr/nugetCache/def' does not contain 1.1.1.
Is there a problem?
