MVC 6 reference issue

I have a quite obscure problem with assemblies in mvc6. Just today I installed ASP.NET beta 7 ( from here: beta http://www.microsoft.com/en-us/download/details.aspx?id=48738&fa43d42b-25b5-4a42-fe9b-1634f450f5ee=True) and mvc 6 for my solution (via a nuget command: Install-Package Microsoft.AspNet.Mvc -Pre ), everything worked fine before I added some references like Microsoft.VisualBasic or System.Drawing. Now I get ,,the type or namespace name could not be found" for all of them. I am pretty confident that I added the referencies to the assemblies. Anyone else encountered this issue ? Tried creating a new project and adding the same references- same problem. Also, intellisense is working fine, it has problems with references only at build-time.

UPD: here is the project.json

{
  "webroot": "wwwroot",
  "version": "1.0.0-*",

  "dependencies": {
    "Microsoft.AspNet.Mvc": "6.0.0-beta7",
    "Microsoft.AspNet.Server.IIS": "1.0.0-beta7",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-beta7"
  },

  "commands": {
    "web": "Microsoft.AspNet.Hosting --config hosting.ini"
  },

  "frameworks": {
    "dnx451": {
      "dependencies": {
        "SpreadsheetGear2012.Core": "1.0.0-*",
        "SpreadsheetGear2012.Drawing": "1.0.0-*"
      },
      "frameworkAssemblies": {
        "Microsoft.VisualBasic": "10.0.0.0",
        "System.Drawing": "4.0.0.0"
      }
    },
    "dnxcore50": { }
  },

  "publishExclude": [
    "node_modules",
    "bower_components",
    "**.xproj",
    "**.user",
    "**.vspscc"
  ],
  "exclude": [
    "wwwroot",
    "node_modules",
    "bower_components"
  ]
}

The issue is that you are targeting both dnx451 and dnxcore50 but only add a dependency to System.Drawing and Microsoft.VisualBasic in dnx451. When you compile, it doesn't know how to resolve the System.Drawing and Microsoft.VisualBasic namespaces when compiling against dnxcore50. To resolve it, you can either:

Remove the target to dnxcore50 in your project.json:

"frameworks": {
  "dnx451": {
    "dependencies": {
      "SpreadsheetGear2012.Core": "1.0.0-*",
      "SpreadsheetGear2012.Drawing": "1.0.0-*"
    },
    "frameworkAssemblies": {
      "Microsoft.VisualBasic": "10.0.0.0",
      "System.Drawing": "4.0.0.0"
    }
  }
},

or compile with #if DNX451 wherever you use System.Drawing or Microsoft.VisualBasic:

public void MyMethod()
{
#if DNX451
    var bmp = new System.Drawing.Bitmap("file");
#endif
}
