Typing Microsoft.EntityFrameworkCore into the Nuget package manager returns nothing and instead displays the NO package found message. The PM console prints the following error text when NuGet\Install-Package Microsoft.EntityFrameworkCore -Version 8.0.3 is entered:

PM> NuGet\Install-Package Microsoft.EntityFrameworkCore -Version 8.0.3

    Hi @Jason Starbuck , Welcome to Microsoft Q&A,

    I am currently using Microsoft Visual Studio Community 2022 (64-bit) - CurrentVersion 17.9.3, and the problem you mentioned does not exist.

    I use .Net Framework.

    You probable have configured nuget for offline mode, but never installed Microsoft.EntityFrameworkCore in the offline cache.
