Microsoft.NETCORE.app dependency not resolved in VS 2015

Question

I am having issues with Visual Studio 2015 that when I create a new CORE 1.0 project the references show an error that says that .NETCoreApp cannot be resolved. When I open the project.json file Microsoft.NETCore.App is underlined and the solution to fix it is to "sort properties".

I have installed VS 2015 update 3 and also .net core tools preview 2.

The sort properties does work but I also notice that intelisense is broken in the projects.json file when trying to add dependencies.

I am a newbie to .net and VS2015 and I am trying to work out of books and tutorials.

Thanks

Answer 1

Resolved.... I failed to add that this was a Windows 10 VM running in parallels on MAC and the projects directory was defaulted to the MAC home drive so it looked like a UNC share "\\MAC\\Home\\" etc. Once I changed to saving to a letter drive everything looked good. Thanks to a coworker that started remembering that he had the same issue a long time ago. Thanks Nate for trying to help.

Answer 2

Resolved...

Entered tools -> Nuget Package Manager -> Manage Nuget Packages For Solution

And uninstalled Microsoft.AspNetCore.Server.ISSIntegration then reinstalled it.

It automatically got all the other dependencies here

"dependencies": { "Microsoft.NETCore.App": { "version": "1.0.1", "type": "platform" }, "Microsoft.AspNetCore.Diagnostics": "1.0.0", "Microsoft.AspNetCore.Server.IISIntegration": "1.1.0", "Microsoft.AspNetCore.Server.Kestrel": "1.0.1", "Microsoft.Extensions.Logging.Console": "1.0.0" },

Then Restarted Visual Studio and solution build succeeded.
