I'm using Windows Server 2016 and ADFS 4.0.
As part of the troubleshooting AD Federation service, which requires me to install the NuGet and the Modules as per https://adfshelp.microsoft.com/diagnosticsanalyzer/Analyze
This is what I have executed and the error:
Install-Module -Name ADFSToolbox -Force
Import-Module -Name ADFSToolbox -Force
Install-PackageProvider -name NuGet -MinimumVersion 2.8.5.201 -Force
Error:
