Errors creating ASP.NET Core 1 application

Question

I have VS2015 and I am attempting to create an ASP.NET Core 1.0 application.

I select the template and also leave the defaults (host in azure and identity security set to individual).

I enter the details for the Azure instance and then when the project loads in VS2015 it errors straight away against DNX 4.5.1 and DNX Core 5.0. I have tried package restore but no luck. in the project.json file I have:

  {
    "frameworks": {
    "dnx451": { },
    "dnxcore50": { }
  },

@Adrien got me onto the right track. I used the Nuget command line to install the latest release for Newtonsoft.Json. It successfully installed and I could see the change to the version in the project.json file. However I still had the same error displaying. Although it had updated the main file, the project.lock.json file didn't get it's references updated at the same time. I had to close my project and re-open before the reference change took effect to the lock file.
