VS2015 not compatible with dotnet-core cli

Question

I cannot make VS2015 work with dotnet cli - I would like to edit and test may dotnet-core project using VS2015 and then have the ability to compile & run it using dotnet cli. However all my attempts to make it so were not successful, which is not ideal - I am aming for writing code on Windows and then using Travis-Ci for bulding.

So this is what is happening:

VS2015 -> Dotnet cli

If I create VS2015 “Console Application” Project (Target .Net Framework 4.6.1) for net-core, I get the following project.json:

{
  "version": "1.0.0-*",
  "description": "ConsoleAppTest Console Application",
  "authors": [ "Nemo" ],
  "tags": [ "" ],
  "projectUrl": "",
  "licenseUrl": "",

  "compilationOptions": {
    "emitEntryPoint": true
  },

  "dependencies": {
  },

  "commands": {
    "ConsoleAppTest": "ConsoleAppTest"
  },

  "frameworks": {
    "dnx451": { },
    "dnxcore50": {
      "dependencies": {
        "Microsoft.CSharp": "4.0.1-beta-23516",
        "System.Collections": "4.0.11-beta-23516",
        "System.Console": "4.0.0-beta-23516",
        "System.Linq": "4.0.1-beta-23516",
        "System.Threading": "4.0.11-beta-23516"
      }
    }
  }

This project compiles and runs just fine when used by VS2015. But as net-core point is cross-platform compatibility, I would like to restore and build it via dotcore cli (and for example, do CI builds on Travis-ci). When running dotnet restore inside this project, I get the following error:

The same error appears while attempting to dotnet restore it on Ubuntu 14.04 Trusty in Travis CI, but except win7-x86 is replaced with Ubuntu.

Dotnet CLI -> VS2015

If I create a new project using dotnet new command, I get the following project.json:

{
    "version": "1.0.0-*",
    "compilationOptions": {
        "emitEntryPoint": true
    },

    "dependencies": {
        "NETStandard.Library": "1.0.0-rc2-23811"
    },

    "frameworks": {
        "dnxcore50": { }
    }
}

This project compiles and runs just fine when run from dotnet command. But I would like to make it work with VS2015 as it is very comfortable IDE – so I open project.json as a project, everything seems to be working (no conflicts or errors in dependencies shown).

I add commands entry to json: “commands”: { “ConsoleAppTest2”: “ConsoleAppTest2”} and hit CTRL+F5 - I am therefore greeted with following error:

System.IO.FileLoadExpection: Could not load file or assembly 'System.Runtime, Version=4.1.0.0, Culture=neutral, PublicToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definiton does not match the assembly reference. (Exception from HRESULT: 0x80131040)

    at System.Reflection.RuntimeAssembly.GetEntryPoint(RuntimeAssembly assembly, ObjectHandleOnStack retMethod)
    at System.Reflection.RuntimeAssembly.get_EntryPoint()

I have just started working with net-core and have no clue how to solve this. I fear it might have to do with VS2015 using old version of dotnet core ( while opening dotnet new created project, VS2015 output of restoring packages contains the following line: C:\Users\{user}\.dnx\runtimes\dnx-clr-win-x86.1.0.0-rc1-update2\bin\dnx.exe ). If this is of importance, I have installed dotnet cli from msi.install long after VS2015 was installed.

The stats I think may be useful:

Your assumptions is correct. The tooling in VS is not up to date yet. Microsoft has a internal release of the visual studio tooling just two weeks ago for the dotnet CLI. A LOT has changed between RC1 (VS2015.2 dnx based tooling) and the new dotnet CLI which is not yet released.

Wait two weeks. RC2 is coming, most probably with tooling support.
