Visual Studio 2019 F# NU1101 Unable to find package FSharp.core

I'm just starting with Microsoft Visual Studio and F#.

I have followed their tutorial as close as I can but when I try to run the code they tell me to I get the error:

NU1101: Unable to find package FSharp.Core. No packages exist with this id in source(s): Microsoft Visual Studio Offline Packages

the entire code I have in the file looks like:

module HelloSquare

let square x = x * x

[<EntryPoint>]
let main argv =
    printfn "%d squared is: %d!" 12 (square 12)
    0 // Return an integer exit code

How can i fix this? Any help would be appreciated and I absolutely am willing to provide more info if it will help tackle the problem.

edit: its a .NET core project

here's the tutorial I'm following: https://learn.microsoft.com/en-us/dotnet/fsharp/get-started/get-started-visual-studio

here is the installation tutorial i followed I did the visual studio section, not the visual studio code, mac, or servers sections: https://learn.microsoft.com/en-us/dotnet/fsharp/get-started/install-fsharp#install-f-with-visual-studio

How would I switch to online nuget source?

Check that you have at least one nuget source configured using:

dotnet nuget list source

it should return something like:

Registered Sources:
  1.  nuget.org [Enabled]
      https://api.nuget.org/v3/index.json

If you don't have any sources configured then use dotnet nuget add source to add one.

e.g.:

dotnet nuget add source https://api.nuget.org/v3/index.json -n nuget.org

I think this may be an issue with current version of dotnet core (5.0.6)
