Those are the only errors which I am getting. From there after, what happens is that my development URL ends up being like this: https://myurl.com/#

Maybe there are packages that I shouldn't load on this version of Visual Studio but I am kind of blocked with the matter so far. I modified my installation while I was getting a different error before which was this:

2) ERROR THROWN BEFORE I MODIFIED MY ASP.NET CORE PACKAGES ON VISUAL STUDIO

Microsoft.Data.SqlClient: Microsoft.Data.SqlClient is not supported on this platform.

I succeeded bypassing it but again I have all these exceptions that are being thrown on my Nuget console on the first point which I already pointed out.

Thanks

The solution to the problem was to upgrade to the new version of Visual Studio. It seems that the new version upgrades many parts of the .NET CORE framework and therefore reassigns, by adding or subtracting outdated packages to the installation.
