Newtonsoft.json: Unable to install 10.0.1/10.0.2 via NuGet

Created on 5 Apr 2017 · 3Comments · Source: JamesNK/Newtonsoft.Json

I have tried to install 10.0.1 and 10.0.2 in Visual Studio 2013 and 2015. Version 9.0.1 works just fine. 10.0.1 and 10.0.2 fail with the following error:

For anyone having this issue, the problem is with the URL https://www.nuget.org/api/v2/. Update your application to use https://api.nuget.org/v3/index.json instead and it will install properly

That looks like an error on nuget.org

I suggest you raise it with them

If I replace https://www.nuget.org/api/v2/ with https://api.nuget.org/v3/index.json as you suggest I face another problem when I instal Umbraco, newtonsoft.json metadata throw error.

Error:An error occurred while retrieving package metadata for 'Newtonsoft.Json.10.0.3' from source 'c:\Users\navneet.kaur.defactoinfotech\documents\visual studio 2015\Projects\1\packages'.
