In VS2019, in the Package Manager Console, I start to update all packages of my solution with update-package, but it stops at;
update-package : Unable to find package'System.Management.Automation_PowerShell_3.0'. Existing packages mustbe restored before performing an install or update. At line:1 char:1
- update-package
- CategoryInfo : NotSpecified: (:) [Update-Package], Exception
- FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PackageManagement.PowerShellCmdlets.UpdatePackageCommand
So I right click on my solution and ask to restore nuget packages but then, I have a contradictory piece of information.
All packages are already installed and there is nothing to restore.Time Elapsed: 00:00:00.0759442========== Finished ==========
When I manage solution nuget packages (right click on solution, manage nuget packages for solution), in the updates tabitem, I select all packages and ask for update, I have a:
Severity Code Description Project File Line Suppression StateError Object reference not set to an instance of an object.
Which is not related to my code (build succeeds).
How to proceed ?
