Can not find runtime target for framework .NETCoreApp=v1 compatible with one of the target runtimes

Question

I am trying to migrate an Asp.Net Core RC1 project to RC2 and have been following this documentation and have also followed the instructions for DNX migration to .NET CLI.

Answer 1

I received this error because I used the incredibly broken NuGet Package Manager in Visual Studio 2015 to update my project.json dependencies. It turned this:

"frameworks": {
  "netcoreapp1.0": {
    "dependencies": {
      "Microsoft.NETCore.App": {
        "type": "platform",
        "version": "1.0.1"
      } 
    }
  }
}

into this:

"dependencies": {
  "Microsoft.NETCore.App": "1.1.0"
},
"frameworks": {
  "netcoreapp1.0": {}
}

Bye bye, platform definition!
