Installing System.Net.Http using Install-Package fails with "Dependency loop detected for package"

I am installing packages to a folder using the following pwsh commands:

Register-PackageSource -Location https://www.nuget.org/api/v2 -Name Nuget -ProviderName Nuget -Trusted -force

Install-Package -Name System.Net.Http -ProviderName Nuget -Destination $somedir

It fails with:

Install-Package : Dependency loop detected for package 'System.Net.Http'.
At C:\git\mobiltracker-ps-docker\Publish-PackageDll.ps1:81 char:1
+ Install-Package -Name $Name -ProviderName Nuget -Destination $Source  ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : Deadlock detected: (System.Net.Http:String) [Install-Package], Exception
+ FullyQualifiedErrorId : DependencyLoopDetected,Microsoft.PowerShell.PackageManagement.Cmdlets.InstallPackage

It looks like the offending package is System.Diagnostics.DiagnosticSource v4.6.0

Workaround:

Installing in the current order works:

1. Install-Package System.Diagnostics.DiagnosticSource -RequiredVersion 4.5.1 -Provider nuget
2. Install-Package System.Net.Http -Provider nuget
3. Install-Package System.Diagnostics.DiagnosticSource -Provider nuget

I opened an issue (https://github.com/dotnet/corefx/issues/41532) on dotnet core repo, but it seems to be related to this client cmdlets.

@urbantom it’s PowerShell implementation of Nuget provider, it’s just awful. It works only with packages without dependencies (or maybe simple dependencies). You can install package with skip dependencies parameter, but you might lose some functionality which is sad. Nuget+PowerShell is total lame. See my gist example and compare

I’m seeing the same behaviour with two unrelated packages on Powershell 6.2.5 running on an Ubuntu machine in Appveyor. Here’s some details I was able to capture:
