I am trying to update my app's package to be compatible with .NET Framework 4.8
After I execute the Update-Package nuget command, I get an error mentioned in this link
Then after solving that issue, when I execute again the Update-Package, I'm now getting this error:
Executing nuget actions took 10.93 min
Update-Package : This collection is read-only.
At line:1 char:1
+ Update-Package -Reinstall -verbose
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Update-Package], Exception
+ FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PackageManagement.PowerShellCmdlets.UpdatePackageCommand
I don't know where to check this because it didn't say which library or files are affected by this error.
I tried to clean the packages, enabled verbose flag and everything that was suggested to the search but to no luck
Has somebody encountered the same and overcome this issue?
Really need help on this one.

I just ran into this on one of my co-worker's machine. The solution was:
Uninstall EF NuGet package
Manually remove Entity Framework sections from the Web.Config/App.Config files
Close Visual Studio
Re-open the solution in Visual Studio
Reinstall the EF NuGet Package
So openn the solution folder in file explorer, can you find the .dlls they are looking for in "Packages" folder then EntityFramework 6.0.1 folder? If not, there are two options:
Check your source control server, there is a possibility it was not downloaded to local workspace. if so, just get them manually from source control explorer if you are using TFS.
If the files were not on source control server either, I would recommend to uninstall EF 6.0.1 nuget, then manual delete the whole folder about ef in the Package folder above, and then reinstall it.
I had the same problem. My project was stored in a network drive. There are many security policies applied to my PC. I moved my project to the local hard drive, and the problem was solved.
It seems like "EntityFramework.Powershell.utility.dll" is tring to use some powershell functionality, and the system is preventing to execute such calls, maybe because the dll that is calling powershell is not a local file.
In your case, make sure that you do not have any security policy or system configuration that would prevent your system execute the problematical extension from a non local drive (EntityFramework.Powershell.utility.dll)
Faced similar problem. Reason of the problem was shifting of my code from one machine to another...Removing and then reinstalling entity framework solved the problem.
Update the Entity Package from Package Manager Console or browser.
please help me to resolve this error:
