Add a Nuget.Config to the current or a parent folder with this. It configures feeds for the most recent runtime versions.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="AspNetVNext" value="https://www.myget.org/F/aspnetvnext/api/v2" />
    <add key="WebStack Nightly" value="http://www.myget.org/f/aspnetwebstacknightly/" />
    <add key="AzureAd Nightly" value="http://www.myget.org/F/azureadwebstacknightly/" />
    <add key="NuGet.org" value="https://nuget.org/api/v2/" />
  </packageSources>
</configuration>

In your global.json add this:

{
    "projects": [ "src", "test" ],
    "sdk": {
        "version": "1.0.0-beta6"
    }
}

Then, in PowerShell run this, to upgrade DNVM.

Branch='dev'; iex (new-object net.webclient).DownloadString('https://raw.githubusercontent.com/aspnet/Home/dev/dnvminstall.ps1')

Then run this to install the beta6 DNX.

dnvm upgrade -u

Beta6 of the runtime should now be available. Here’s an example directory structure.

MyApp
    .git
    Nuget.Config
    etcetara
    AppSolution
        AppSolution.sln
        global.json
        etcetara
        src
            App
                project.json
                etcetara

Note, with Visual Studio 2015 RC, we might have to do the following:

cd ~\.dnx\runtimes
rni .\dnx-clr-win-x86.1.0.0-beta6-12085 .\dnx-clr-win-x86.1.0.0-beta6
