AspNetCore namespace doesnt exist

Question

I'm following this course to learn ASP.NET Core.

I did exactly as they did, I can type dotnet new and dotnet restore. I also installed the dotnetcore 1.0.1 SDK preview.

All seems fine, and I should be able to type

using Microsoft.AspNetCore.Http;

But the only things recognized after Microsoft are cSharp, visualbasic and win32?

Here is my project.json file:

 {
   "version": "1.0.0-*",
   "buildOptions": {
   "debugType": "portable",
   "emitEntryPoint": true
  },
  "dependencies": {},
  "frameworks": {
   "netcoreapp1.0": {
    "dependencies": {
    "Microsoft.NETCore.App": {
      "type": "platform",
      "version": "1.0.1"
    },
    "Microsoft.AspNet.WebApi": "5.2.3",
    "Microsoft." **<< i cannt type AspNetCore here**
    },
   "imports": "dnxcore50"
   }
 }

There is no Microsoft."AspNetCore". The only things I do have starting with Asp are:

AspNet.Identity.Owin
AspNet.Mvc
AspNet.Providers.Core
AspNet.Razor
AspNet.SignalR
AspNet.Web.Optimization
AspNet.WebApi
AspNet.WebApi.Clients
AspNet.WebApi.Core
AspNet.WebApi.Cors
AspNet.WebPages

i'm using visualstudio code (as in the coarse) at the moment but same thing happens when i load the json as a project file in vs2015 — Peter

Type "Microsoft.AspNetCore and press CTRL+spacebar and check — Sanket

it eventually worked, i think the problem is because its so new, it wasnt recognized when editing the json file when i typed but after giving the :"" for version selection, it did came up with the version. the code completion wasnt woking, not entirely sure how it got fixed, but for the record i had the machine reinstall aspnetcore sdk and restarted the machine — Peter

The code completion doesn't always work when editing the project.json file, especially if you're using a lighter editor like VS Code. (Sometimes it doesn't work even in full-blown Visual Studio).

If this happens, don't worry! You can still install any packages you need. Find packages by searching on NuGet and then edit the dependencies section like this:

"PackageName": "1.0.0"   # Version from package details on NuGet

Then, use the dotnet restore command within the project directory to pull down all the packages in project.json.
