When I add Nuget packages via the Visual Studio 2015 GUI some packages don't install with the following error
Access to the path 'Microsoft.DotNet.InternalAbstractions.dll' is denied.
I tried running Visual Studio 2015 as Administrator and uninstalling the packages and adding them again but I still get the same error
回答1:
I closed Visual Studio and killed the 2 running processes called dotnet as well as deleted the C:\Users\myser.nuget\packages folder to ensure all packages are redownloaded again in case something was corrupt.
回答2:
Go to the dll path and make sure to give the right permission access to the local machine :
I usually do the below :
1- Untick the Read-only field :
2- Add the missing user access :

I close my Visual Studio.. and start it again as an administrator... It Worked.
