Answer 1

Add the following to your project.json:

Under dependencies:

"Microsoft.VisualStudio.Web.CodeGenerators.Mvc": {
    "version": "1.0.0-preview2-final",
    "type": "build"
}

Under tools:

"Microsoft.VisualStudio.Web.CodeGeneration.Tools": {
    "version": "1.0.0-preview2-final",
    "imports": [
        "portable-net45+win8"
    ]
}

• Version number may change depending on which version of .NET Core you're using in your project
• You may get another error about Microsoft.DotNet.InternalAbstractions missing, in which case you'll need to get from NuGet
• Make sure "Microsoft.VisualStudio.Web.CodeGeneration.Tools" version in dependencies matches "Microsoft.VisualStudio.Web.CodeGeneration.Tools" version in tools
