Bug - VSO Build Prebuild.ps1 CoreClr

[Eneuman]

Using the latest dnvm seems to break VSO builds.
(To reprocude this issue, follow the information in this post: https://msdn.microsoft.com/en-us/Library/vs/alm/Build/azure/deploy-aspnet5 )

My Prebuild.ps1 has this block:

echo "Installing clr"
& $env:USERPROFILE.dnx\bin\dnvm install $dnxVersion -r clr -Persistent
echo "Installing coreclr"
& $env:USERPROFILE.dnx\bin\dnvm install $dnxVersion -r coreclr

(The rest of it has not been changed)
Installing just clr works great and the build finish successfully.
But then I try to also install coreclr I get this error message:

One quick thing to help diagnose this, if you switch the order so that it does coreclr first then what's the result?

I don't have all the code handy right now but I am wondering if persisting the change of desktop clr before installing coreclr is breaking something on the subsequent run. It is most likely a bug, but I want to narrow it down a bit.

I just tried to switch the order and got the same error message. Using only coreclr worked fine (& $env:USERPROFILE.dnx\bin\dnvm install $dnxVersion -r coreclr -Persist)

The error seems to occure when installing more then one runtime. I also tried to run it without -Persist but it didn't work ither.

I also noted that running "dnvm install 1.0.0.-beta7 -r coreclr" on my local machine and directly afterwards running "dnvm install 1.0.0.-beta7 -r clr" didn't work ither. I get the following error: "'dnvm' is not recognized as an internal or external command,operable program or batch file."
This used to work in the previous version.

Adding the following two lines to Prebuild.ps1, just above "# install DNX", solved the issue.

$env:DNX_HOME="C:\Users\buildguest.dnx"
$env:DNX_GLOBAL_HOME="C:\Users\buildguest.dnx"

This fixed that problem. I hadn't noticed that the path is actually C:\Users\buildguest\.dnx\

$env:DNX_HOME="$ENV:USERPROFILE\.dnx"
$env:DNX_GLOBAL_HOME="$ENV:USERPROFILE\.dnx"

But I get now another problem when building in Azure in the execution environment

As I understood it's due to an old web tooling. How do I modify that in Azure?
