For my Package Source, I've tried both the following, to no avail. I've even tried Install-Package EntityFramework, and same error.
https://www.nuget.org/api/v2/
https://api.nuget.org/v3/index.json
You can try the following solutions to cope with your issue:
Solution # 1
Delete all the folders inside of the packages folder.
Update all packages in Nuget Package Manager.
Solution # 2
type in the package manager console Uninstall-Package EntityFramework -force, then delete the EntityFramework Folder in Package Folder, and then install it again Install-Package EntityFramework
Solution #3
Use the following link : https://docs.nuget.org/Release-Notes/Known-Issues
From the VS command prompt, run the following command:
regsvr32 "C:\Program Files (x86)\Common Files\microsoft shared\MSEnv\VsLangproj.olb"
Solution #4
Clear the package Cache:
Tools->package Manager->Package Manager Settings-> Clear Package Cache
I hope one of the above methods will help you solve the issue.

I am trying to install a few online or external packages into my project using nuget in Visual Studio 2017. I tried the package console and it fails. The problem seems to be that the only package source I have available as an option is "Microsoft Visual Studio Offline". There is no "All" option in the package source drop down at the top of the package console, which I believe I need to see if I am trying to add online packages. I have searched all over the place for what might be a simple answer, but all answers seem to deal with other related matters and not specifically this one. Maybe I didn't type the correct phrase to yield results, but I tried and couldn't find them. What am I missing? A setting? Not the correct license? Thanks.

The NuGet team deprecated solution level packages in NuGet 3.0. So install the NuGet package to solution without any project is not supported. You need create a project, then add the package to the project.

i don't understand any of that, what is wrong?
Ensure that you have a proper NuGet source defined. You can go to Tools -> Options -> NuGet Package Manager -> Package Sources to make sure. i.e.: https://api.nuget.org/v3/index.json
Secondly you should double check that your NuGet version is the latest. Go to Tools -> Extensions and Updates and update if you aren't on the latest version.
Finally you could also try to manually download the package from https://www.nuget.org/packages/Xamarin.Android.Support.Design/ and setup a local NuGet repository to ensure that works. Chances are one of the first bullets should fix this.

Check if you already have Newtonsoft.Json reference added in packages.config. If yes, delete Newtonsoft.Json entry and retry Install-Package.
Sometimes just removing it from packages.config might not be enough. I had to remove the Newtonsoft.Json directory from the packages-directory, after that installing worked.
