Building ASP.NET 5 project in VSO

Question

I cannot get VSO to build ASP.NET 5 projects. There seems to be an issue getting the packages.

Build steps in VSO:

I have the project building in VS 2015 and have "Restore NuGet Packages" checked.

Build console output:

Note that this is specific to NuGet package restore. Refer to my answer for the fix.

Answer 1

I used the following step to install DNVM, DNX and to call dnu restore for each project.json file found in src:

# bootstrap DNVM into this session.
&{$Branch='dev';iex ((new-object net.webclient).DownloadString('https://raw.githubusercontent.com/aspnet/Home/dev/dnvminstall.ps1'))}

# load up the global.json so we can find the DNX version
$globalJson = Get-Content -Path $PSScriptRoot\global.json -Raw -ErrorAction Ignore | ConvertFrom-Json -ErrorAction Ignore

if($globalJson)
{
    $dnxVersion = $globalJson.sdk.version
}
else
{
    Write-Warning "Unable to locate global.json to determine using 'latest'"
    $dnxVersion = "latest"
}

# install DNX
# only installs the default (x86, clr) runtime of the framework.
# If you need additional architectures or runtimes you should add additional calls
# ex: & $env:USERPROFILE\.dnx\bin\dnvm install $dnxVersion -r coreclr
& $env:USERPROFILE\.dnx\bin\dnvm install $dnxVersion -Persistent

 # run DNU restore on all project.json files in the src folder including 2>1 to redirect stderr to stdout for badly behaved tools
Get-ChildItem -Path $PSScriptRoot\src -Filter project.json -Recurse | ForEach-Object { & dnu restore $_.FullName 2>1 }
