The dependency microsoft.aspnetcore.mvc 1.0.0 does not support framework .NETCoreApp, Version=v1.0

Question

Trying to create an ASP.NET Core project given that it has just reached RTM. I created a new project using the Visual Studio 2015 Update 3 template called 'ASP.NET Core Web Application (.NET Core)'. I then went to the Nuget Package Manager and updated all the package.json packages to 1.0.0. Visual Studio fails to restore the package with the error in the title of this post.

Here is the project.json after updating Nuget Packages:

{ 
  "dependencies": {
    "Microsoft.AspNetCore.Mvc": "1.0.0",
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.0",
    "Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0",
    "Microsoft.Extensions.Configuration.FileExtensions": "1.0.0",
    "Microsoft.Extensions.Configuration.Json": "1.0.0",
    "Microsoft.Extensions.Logging": "1.0.0",
    "Microsoft.Extensions.Logging.Console": "1.0.0",
    "Microsoft.Extensions.Logging.Debug": "1.0.0",
    "Microsoft.NETCore.App": "1.0.0"
  },

  "tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": {
      "version": "1.0.0-preview-final",
      "imports": "portable-net45+win8+dnxcore50"
    }
  },

  "frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "dnxcore50",
        "portable-net45+win8"
      ]
    }
  },

  "buildOptions": {
    "emitEntryPoint": true,
    "preserveCompilationContext": true
  },

  "runtimeOptions": {
    "gcServer": true
  },

  "publishOptions": {
    "include": [
      "wwwroot",
      "Views",
      "appsettings.json",
      "web.config"
    ]
  },

  "scripts": {
    "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
  }
}

The output from the Nuget Package Manager:

Package Microsoft.AspNetCore.Mvc 1.0.0 is not compatible with netcoreapp1.0 (.NETCoreApp,Version=v1.0). Package Microsoft.AspNetCore.Mvc 1.0.0 supports: - net451 (.NETFramework,Version=v4.5.1) - netstandard1.6 (.NETStandard,Version=v1.6)

Answer 1

Did you remember to install: .NET Core Tools for Visual Studio? You can get that here.

Take a look at Scott Hanselman's Blog.

Answer 2

NetCoreApp needs to be of type 'platform'.
