Bad error message if Microsoft.NETCore.App isn't a "platform" in the project.json

Steps to reproduce

Create a new project/exe that uses the netcoreapp1.0 framework.

Add a dependency “Microsoft.NETCore.App”:“1.0.0-rc2-24015”

Expected behavior

A better error saying that the type needs to be a platform. The entry should be “Microsoft.NETCore.App”: { “version”: “1.0.0-rc2-24015”, “type”: “platform” } And that fixes the error correctly.

Actual behavior

Errors that suggest putting in RID’s

Hopefully this helps someone, I ran into this error message after upgrading some nuget packages in an ASP.NET Core project.

My project.json file had this line before nuget upgrade: "Microsoft.NETCore.App": { "version": "1.0.1", "type": "platform" }

Then after upgrade, that line was removed and this was added: "Microsoft.NETCore.App": "1.0.1"

Since this now doesn’t list the platform (the focus of this GitHub issue), you just need to revert the newly added line to the previous block (with the “type”: “platform”).

@wilfredogr the solution is to add type: platform to the Microsoft.NETCore.App dependency, like so:

"Microsoft.NETCore.App": {
    "type": "platform",
    "version": "1.1.0"
}
