At line:1 char:1
Install-Package Microsoft.AspNet.MVC
CategoryInfo : NotSpecified: (:) [Install-Package], Exception

Nuget Package Manager - Update-Package NotSpecified error

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.

Service Start and stop in Universal Windows App

I found the following Links in MSDN to help me start and stop the window services.
There is code snippet which tells it is possible to start and stop the service.
ServiceController sc = new ServiceController("Telnet");
if ((sc.Status.Equals(ServiceControllerStatus.Stopped))
|| (sc.Status.Equals(ServiceControllerStatus.StopPending)))
{
sc.Start();
}
else
{
sc.Stop();
}
sc.Refresh();
for this i need the System.ServiceProcess.dll the dll.
Namespace: System.ServiceProcess
Assembly: System.ServiceProcess (in System.ServiceProcess.dll)
I am trying to add this from NUget and got the error.
Type Script command :
Install-Package System.ServiceProcess.ServiceController -Pre
Error Message :
Install-Package : System.ServiceProcess.ServiceController 4.1.0-beta-23516 provides a compile-time reference assembly for System.ServiceProcess.ServiceController on UAP,Version=v10.0, but there is no run-time assembly compatible
with win10-arm.

+ Install-Package System.ServiceProcess.ServiceController -Pre
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Install-Package], Exception
+ FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PackageManagement.PowerShellCmdlets.InstallPackageCommand

This namespace System.ServiceProcess cannot be supported in uwp. We cannot find this .Net api in .NET for UWP apps.
Also you can add this reference manually by download the package from System.ServiceProcess.ServiceController. But you will still receive error when you run the code.
