Dependencies : values located in this section refer to installed NuGet packages.

Commands: ASP.NET Core 1.0 supports command line tools. This section allows for you to configure commands that can be run in the command line. Project.json file. For example when running dnx.exe you can pass the name of a command to execute it. In the code below you could run “dnx . web” to self host the app on Windows or “dnx . kestrel” to run your app on OS X/Linux.

{
  "commands": {
    "web": "Microsoft.AspNet.Hosting server.name=Microsoft.AspNet.Server.WebListener server.urls=http://localhost:5001",
    "kestrel": "Microsoft.AspNet.Hosting --server Kestrel --server.urls http://localhost:5004",
    "ef": "EntityFramework.Commands"
  },

Frameworks: this section is used to target frameworks that will be built, and dependencies required for configuration. For example dnx451 target the desktop and dnxcore50 targets Core CLR.

exclude & publishExclude: both these sections as the name suggests identifies files, folders and content potions of the project that need to be excluded from the build and publishing the site.

global.json

Is used to configure the solution as whole, and is made up of project and sdk.

{
  "projects": [ "src", "test" ],
  "sdk": {
    "version": "1.0.0-rc1-update1"
  }
}

projects designates which folder contains source code, and sdk specifies the version of dnx that VS 2105 will use for your solution.

wwwroot folder

Is the root of your web application when running on a webserver, This folder consist of asset that your web app will directly serve to the client , and includes CSS, Images, HTML, libraries and JavaScript files. Note all your code files ( C# and Razor) should exist outside this folder.
