I just started on this project and it is basically empty. When I try to install log4net in nuget package manager, the following error is shown in the output.
A PackageReference for 'Microsoft.NETCore.App' was included in your
project. This package is implicitly referenced by the .NET SDK and you
do not typically need to reference it from your project. For more
information, see https://aka.ms/sdkimplicitrefs
I simply do not understand this message, why it tells me there's a .net core thing in my project?
When it says this package is implicitly referenced, does it mean that I have loaded this package? However, I don't quite believe that since I could not use anything from log4net.
BTW, the same error happens when I try to install an old version of netsoft json.
I created the project as a .NET Standard 1.1 project.
Am I misconfiguring something or I have a totally wrong idea about the whole thing?
