私project.jsonは、次のようになります。

{ 
    "version": "1.0.0-*", 
    "buildOptions": { 
     "debugType": "portable", 
     "emitEntryPoint": true 
    }, 

    "dependencies": { 
     "Microsoft.NETCore.App": { 
      "version": "1.0.1" 
     } 
    }, 
    "frameworks": { 
     "netcoreapp1.0": { 
      "imports": "dnxcore50" 

     } 
    }, 
    "runtimes": { 
     "win7-x64": {}, 
     "ubuntu.16.04-x64": {} 
    } 
} 

Answer 1

はのruntimesセクションを削除しますproject.jsonファイル、または少なくともubuntu.16.04-x64行です。

self-contained applicationをビルドしている場合を除き、runtimesセクションは必要ありません。
