It seems like there is a problem with the "System.Net.Http" dll. I keep getting all kind of errors relating to it: while trying to restore nuget packages (It seems like the framework can not connect to the nuget index:
Unable to load the service index for source https://api.nuget.org/v3/index.json.
even while trying to sign in to the microsoft account through the Visual studio 2019 community:
we could not refresh the credentials for the account ...
Could not load file or assembly System.Web.Http, Version=5.2.2.0
It seems like a system problem. Where should I look\locate this dll in system level ? PLEASE HELP
