That looks pretty wrong…

@Petermarcu @shawnwildermuth I just got it to work, though I can’t say I definitely understand the cause. Here is my info and theory:

nuget.config

<configuration>
  <packageSources>
    <add key="dotnet-core" value="https://dotnet.myget.org/F/dotnet-core/api/v3/index.json" />
    <add key="AspNetCI" value="https://www.myget.org/F/aspnetcirelease/api/v3/index.json" />
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
  </packageSources>
</configuration>

Broken (dotnet new generated)

  "dependencies": {
    "Microsoft.NETCore.App": {
      "type": "platform",
      "version": "1.0.0-rc2-3002416"
    }
  }

Working:

  "dependencies": {
    "Microsoft.NETCore.App": {
      "type": "platform",
      "version": "1.0.0-rc2-*"
    }
  },

In the project.lock.json all of the dependencies in the broken scenario are all referencing rc3. I suspect that something was recently pushed to a myget feed referencing rc3. Something about dotnet restore is potentially not respecting a version lock or something with the way the explicit version is written in project.json. By using the wildcard match, I believe I’m forcing it to respect rc2.
