NCrunch was unable to restore Nuget packages required to build a test environment for this project, due to an unspecified failure when invoking 'msbuild.exe /t:restore'

The following packages do not exist under the Nuget packages folder for the active user profile, yet they have been flagged by NCrunch as potentially needed for normal operation. NCrunch has attempted to restore these files via an MSBuild restore step, which has either failed or not returned the expected result. It's possible that these packages may not be needed for building projects or running tests in your environment. If you experience downstream problems with NCrunch on this solution, it is recommended you restore or download the packages manually.


Is there a way to tell NCrunch where Nuget Packages are?
What does Ncrunch think "Nuget packages folder for the active user profile" is ? Where does it get that info from ?

I have tried setting the documented nuget environment variables.
NUGET_HTTP_CACHE_PATH=the location
NUGET_PACKAGES=the location

There is a nuget.config files at Machine level.
C:\Program Files (x86)\NuGet\Config\Nuget.config
and
C:\Program Files (x86)\NuGet\Config\Microsoft.VisualStudio.Offline.config
both have the same content
<add key="Microsoft Visual Studio Offline Packages" value="the location"/>


There is a maintained file at user level
C:\Users\<user>\AppData\Roaming\NuGet\nuget.config
with
<config>
<add key="repositoryPath" value="the location" />
</config>

There are no project or solution level nuget package settings.

So Ncrunch should be able to find the packages.

Can I see why Ncrunch cant find packes or tell it which directories to use ?

EDIT: AFTER POSTING THIS, IT now works
not sure if was permissions on directories, an extra restart of VS or Ncrunch engine.

But I can now see Ncrunch working.
Sorry for any inconvenience

I'm glad you managed to solve this. For a bit of background, this is a step NCrunch does to restore packages that it needs internally if it can't find the packages already installed in your user's .nuget directory. The package restore step is dependent on operation of a whole lot of stuff under the hood (MSBuild, .NET Core, Nuget, network, etc), so there are situations it can fail.

If you see this again, try creating a simple project that references the missing packages in Visual Studio. This will trigger VS to restore them to your user profile where NCrunch can find them.
