Hi Code,
Thanks for contacting Syncfusion support.
#1) The reported issue (“when I run "dotnet restore" I get the following log”) may occurs if you have referred the online feeds other than the below online feeds (ASP.NET Core and nuget.org). Please ensure that you have referred this two online feeds and no other local packages in your application.
#2) Also ensure that you have installed VS2015 and ASP.NET Core Preview 2 in your machine.
If still issue persists, please share the project ‘References’ section in expanded view, also share the complete results of output window when restore the packages. This will be helpful for us to analyze and provide a solution at the earliest.
Regards,
Francis Paul A
