.Net Core 1.1.0 Visual Studio Tooling

I've just migrated a asp.net core project from 1.0.1 to 1.1.0 and when running dotnet run or dotnet restore I get the following message

C:\Users\you\Desktop\API\src\API\API.xproj(7,3): error MSB4019: The imported project "C:\Program Files\dotnet\sdk\1.0.0-preview4-004110\Extensions\Microsoft\VisualStudio\v14.0\DotNet\Microsoft.DotNet.Props" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.

I've installed all the SDK and runtimes, but still can't neither create .Net Core 1.1.0 projects in visual studio nor restore in console my packages.

The project.json is as follows, supposedly the migration is right, but still can't figure it out.

The problem was in the global.json of my solution the version property, I had it changed to 1.0.0-preview2-1-003177 and it worked.

{
  "projects": [ "src", "test" ],
  "sdk": {
    "version": "1.0.0-preview2-1-003177" //Previously 1.0.0-preview2-003131
  }
}

You need to download .NET Core 1.1 SDK - Installer from Microsoft website. If you can download only runtime as well. Below is the url for the same.
