Creating new project (following Beefball tutorial) results in multiple missing dependency errors

[vivid-pixel]

I installed all prerequisites from: https://docs.flatredball.com/flatredball

I'm attempting to follow the tutorial for Beefball: ttps://docs.flatredball.com/flatredball/tutorials/beefball/creating-a-glue-project

I cannot get the project to build in Visual Studio 2022 due to these missing packages:

Can you open your .csproj file and look at which nuget packages are referenced? It looks like you are referencing MonoGame.Framework.DesktopGL but that is missing.

Things to try/do:

1. Can you paste the contents of your .csproj?
2. Are you able to add other nuget packages to visual studio projects? What if you create a new console app and add a common library like Newtonsoft JSON.net?
3. Can you take a screenshot of your nuget sources in Visual Studio?

I'll be happy to answer questions here, but if you want to join discord I may be able to help more quickly too.

For the 2nd question, I'm not sure, as I'm new to C# and Visual Studio (not to programming as a whole). This is an out-of-the-box setup for Visual Studio 2022 and Flat Red Ball so I was thinking it's just documentation needing to be updated in some way.

Nuget installed sources ("Package source: All"):

• FlatRedBallDesktopGLNet6 (2025.2.17.738)
• MonoGame.Framework.DesktopGL (3.8.1.303)
• Newtonsoft.Json (13.0.3)
• SkiaSharp (2.88.6)

It seems to be a problem restoring nuget packages:

C:\Users\N\OneDrive\Documents\code\c#\Beefball\Beefball\Beefball.csproj 1
Error (active) NU1102 Unable to find package Newtonsoft.Json with version (>= 13.0.3)

This isn't just a FlatRedBall issue, but seems to be a general configuration issue with Visual Studio.

To check your package sources, you can do this:

1. Open Visual Studio
2. Select Tools -> Options
3. Select NuGet Package Manager -> Package Sources
4. Post a screenshot of your page. It might look like this:

Hey, that was it! I needed to add api.nuget.org as a source like you have in your screenshot.
Stride was the only entry listed for package sources, which is an engine I installed today and then uninstalled. Very nice of it to make a breaking change to VS and then not undo that change on its way out.

Thank you for pointing out the missing piece of the puzzle.
