After developing a few ASP.Net Core MVC sites with sorting and searching, that work quite OK, when coming to pagination I met some errors that I did not understand, so I thought working on the demo application would be a good idea.
Well, I get the same errors there: strange, is not it?
I imagine that if there were errors in the demo application that would be well known and quickly corrected, the other hypothesis is an error on my machine.
I hope somebody is able to situate the error, to avoid me the pain of completely reinstalling my machine, which for sure would take … some time, at least.

First of all, the reference page is there: Tutorial: Add sorting, filtering, and paging – ASP.NET MVC with EF Core

On that page, search “Get the code”, and click on “Download or view the completed application”.

I was surprised to see a title that begins with “Aspnet-Docs”, but somebody by Microsoft confirmed me the link was correct.

I arrive there:
https://github.com/dotnet/AspNetCore.Docs/tree/main/aspnetcore/data/ef-mvc/intro/samples/cu-final

then I click on “Code” in the navigation bar on top of the page, then on the “Code” button.

I obtain a “Clone” interface, that gives me this URL to clone:
https://github.com/dotnet/AspNetCore.Docs.git

So, in Visual Studio 2022 I start a new session, click on “Clone a repository”, and paste that URL.

When launching the execution I see nothing persuasive. No application window appears.

After updating Visual Studio 2022 to Version 4.8.09032, I launch execution again, and it raises four errors.

Perhaps it is best to first give the original (localised) version for each from the errors window, before translating it to English.

So, maybe after taking some distance it will be obvious that I forgot to install something. It is possible that somebody can be quicker than I on this.

As I said, when seeing errors in my code, I tried cloning the demo application, and saw, at least partially, the same errors.
