Shutting down another version of dependencies in the dotnet core

Question

I am working on a project that targets netstandard1.6and net451. Unfortunately, I get these warnings when creating my library:

C:\Path\project.json(22,35): warning NU1007: Dependency specified was Microsoft.CSharp >= 4.0.1 but ended up with Microsoft.CSharp 4.0.0.0.
C:\Path\project.json(17,38): warning NU1007: Dependency specified was System.Collections >= 4.0.11 but ended up with System.Collections 4.0.0.0.
C:\Path\project.json(18,30): warning NU1007: Dependency specified was System.Linq >= 4.1.0 but ended up with System.Linq 4.0.0.0.
C:\Path\project.json(19,33): warning NU1007: Dependency specified was System.Runtime >= 4.1.0 but ended up with System.Runtime 4.0.10.0.
C:\Path\project.json(20,49): warning NU1007: Dependency specified was System.Runtime.InteropServices >= 4.1.0 but ended up with System.Runtime.InteropServices 4.0.10.0.
C:\Path\project.json(21,36): warning NU1007: Dependency specified was System.Threading >= 4.0.11 but ended up with System.Threading 4.0.0.0.

This is mine project.json:

{
    "version": "1.0.0-*",
    "description": "MyLibrary",

    "frameworks": {
        "net451": {
        },
        "netstandard1.6": {
        }
    },

    "dependencies": {
        "NETStandard.Library": "1.6.0",
        "Newtonsoft.Json": "9.0.1",
        "MyOtherProject.Common": "1.0.0-*",
        "System.Collections": "4.0.11",
        "System.Linq": "4.1.0",
        "System.Runtime": "4.1.0",
        "System.Runtime.InteropServices": "4.1.0",
        "System.Threading": "4.0.11",
        "Microsoft.CSharp": "4.0.1"
    }
}

The library is built without error targeting netstandard1.6and net451however I get these warnings when building for net451.

Any ideas?

I have the same problem. My fix that removed the warnings was

{
  "version": "1.0.0-*",
  "description": "MyLibrary",

  "frameworks": {
    "net451": {
      "dependencies": {
        "System.Collections": "4.0.0",
        "System.Linq": "4.0.0",
        "System.Runtime": "4.0.10",
        "System.Runtime.InteropServices": "4.0.10",
        "System.Threading": "4.0.0",
        "Microsoft.CSharp": "4.0.0"
      }
    },
    "netstandard1.6": {
      "dependencies": {
        "System.Collections": "4.0.11",
        "System.Linq": "4.1.0",
        "System.Runtime": "4.1.0",
        "System.Runtime.InteropServices": "4.1.0",
        "System.Threading": "4.0.11",
        "Microsoft.CSharp": "4.0.1"
      }
    }
  },

  "dependencies": {
    "NETStandard.Library": "1.6.0",
    "Newtonsoft.Json": "9.0.1"
  }
}

But I think there might be some better solution.
