Packages restore failed

Package restore

Package restore failed in asp.net core 1.1
Note : i am referencing my project to

"frameworks": {
"net461": { }
},

Recently i upgraded my project from asp.net core 1.0 to 1.1 and it works fine on my old laptop by i switched the project to fresh new laptop ,Installed visual studio 15 .here is the configuration of the VS 15

I have also installed the required SDK as mentioned on this link
https://jeremylindsayni.wordpress.com/2016/11/20/upgrading-from-net-core-1-0-t0-1-1-with-visual-studio-2015/

. Now my project json file looks likes this :

and global.json looks like this

{
"projects": [ "." ]
}

but as you can see the packages are not loading as expected.
when i do dotnet restore from the package manager console
i get something like this :

Any Idea ??

It looks like you are still using the unreleased version of everything from late 2015. I would strongly recommend that you upgrade to the supported SDK and tooling. Is there a reason you can't upgrade to the supported .NET Core tooling?

@Petermarcu Thanks for the reply man.. i finally was able to solve the issue but not with the latest version but the version i did the update was ..
Microsoft .Net Core 1.0.1 -SDK 1.0.0 Preview 2- 003131
Microsoft .Net Core 1.0.1 -VS 2015 Tooling Preview 2
and this worked for me.

Glad to hear it worked for you.

Same problem here except the installation of the listed SDK and Tooling did not resolve the issue for me in a particular solution while it did work in others after updating my global.json. I am currently getting dozens of errors in a specific solution of type:

Severity Code Description Project File Line Suppression State
Error NU1002 The dependency Microsoft.AspNetCore.Hosting.Abstractions 2.0.1 does not support framework .NETFramework,Version=v4.6.1.

Where the listed dependencies in project.json are not supported. E.g. error from output:

error: Package Microsoft.Extensions.Logging.Abstractions 2.0.0 is not compatible with net461 (.NETFramework,Version=v4.6.1). Package Microsoft.Extensions.Logging.Abstractions 2.0.0 supports: netstandard2.0 (.NETStandard,Version=v2.0)

Any suggestions other than the nuclear option of removing dotnet 2.1.4 and VS 2017 completely? Upgrading the solution is out of the question for the moment.
