how do I execute a .net core console app on mac os

Question

I just installed Visual studio for MAC, and created the hello world console app when pressing play in the bottom window (application output), I can see the hello world.

However , how do I execute that app from the command/terminal line?

If I try ./myapp.dll I get permission denied, even after sudo su.

so, not sure how to run it

this is my json

{
  "version": "1.0.0-*",
  "buildOptions": {
    "debugType": "portable",
    "emitEntryPoint": true
  },
  "dependencies": {},
  "frameworks": {
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "version": "1.0.0"
        }
      }
    }
  },
  "runtimes": {
    "win10-x64": {},
    "osx.10.10-x64": {}
  }
}

Update

I have run dotnet restore, and dotnetrun, first I got this error: Can not find runtime target for framework '.NETCoreApp,Version=v1.0' compatible with one of the target runtimes: 'osx.10.12-x64'. Possible causes:

Then I changed my project.json like this:

{
  "version": "1.0.0-*",
  "buildOptions": {
    "debugType": "portable",
    "emitEntryPoint": true
  },
  "dependencies": {},
  "frameworks": {
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "version": "1.0.0"
        }
      }
    }
  },
  "runtimes": {
    "win10-x64": {},
    "osx.10.12-x64": {}
  }
}

Then I get hundreds of errors like this: System.Threading.Tasks 4.0.11 provides a compile-time reference assembly for System.Threading.Tasks on .NETCoreApp,Version=v1.0, but there is no run-time assembly compatible with osx.10.12-x64. System.Threading.Timer 4.0.1 provides a compile-time reference assembly for System.Threading.Timer on .NETCoreApp,Version=v1.0, but there is no run-time assembly compatible with osx.10.12-x64.

Just listed a few J

I guess my runtime is incorrect for OSX, but should I set it?

You need to run it with dotnet, like:

dotnet myapp.dll

To my knowledge, the tooling does not yet support Ready to Run (native) binaries, yet.

Your project.json is missing the platform type for the framework. It should look like this:

"netcoreapp1.0": {
  "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.0",
      "type": "platform"
    }
  }
}
