Nuget and The package manager on VS 2022 Community edition cannot find the Microsoft.EntityFrameworkCore

Question

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

Answer 1

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.
