I'm setting up a new PC to do development on. Got VS 2019 Community Edition. I went to install Entity Framework Core, but couldn't. It cannot be found. All that I could find was "Microsoft Visual Studio Offline Packages". I searched on that term and came across this article on the archived MSDN forum on this topic. I tried adding NuGet, following the example on the link I have, using https://api.nuget.org/v3/index.json for the URL. It doesn't work. All I'm getting is errors like this:
[NuGet] The V2 feed at 'https://www.nuget.org/Search()?$filter=IsLatestVersion&searchTerm=''&targetFramework='net5.0'&includePrerelease=false&$skip=0&$top=26&semVerLevel=2.0.0' returned an unexpected status code '404 Not Found'.
How do I resolve this issue?
