dependency could not be resolved

I am trying to build a web site using .net framework core with entity framework core. I created a web project using the ASP.NET Core Web Application (.net core) template with Visual Studio 2015 Professional (update 3). Then I used Nuget to add the Microsoft.EntityFrameworkCore.Tools to the solution.

When I compiled the solution, I got this dependency error - "NU1001 The dependency Microsoft.EntityFrameworkCore.Tools >= 1.0.0-preview2-final could not be resolved". I googled the topic but couldn't find the solution. How can I fix this??

Did you install asp.net core? Check if your package is compatible with your current asp.net core version. – Fabricio Koch
i have .net core 1.01 - vs 2015 tooling preview 2 installed. I did a repair but still have the dependency not resolved issue. – user7002499
Update your question with your project.json. – Fabricio Koch

For those who may run into this problem, you would need to right click on the References and click Restore Packages. That solved the problem.

Have you added the following nuget Packages sources in your nuget package?

https://dotnet.myget.org/F/aspnetcore-ci-dev/api/v3/index.json

You can do so in Tools > Nuget Package Manager Settings > Packages sources

Also, what is your SDK version?

It should be "1.0.0-preview2-003131".
