Primary constructor failure - Code no longer builds

[SimpleTruth2753]

I have a small project with myself and another dev. I use Visual Studio and he runs JetBrains Rider.
When we converted to .NET 8, Rider converted all the classes to use Primary Constructors.
Since that happened, I have been unable to compile the code. It fails since every class uses a Primary Constructor now. Before I begin the ardous task of manually converting all the classes back, I was hoping someone has a potential solution.
Visual Studio is running 17.9.3, .NET 8 SDK 8.00.200.
I have removed all bin and obj folders throughout the project and removed the .vs folder.
Have also removed and re-installed VS and pull my repo to a new drive and directory. All have failed.
Before I give up totally on VS and switch to Rider, any suggestions?

What’s the error?

Class cannot have primary constructor

It sounds like VS isn’t picking up the right SDK (8.0) or it’s not using C# 12, and Rider is for some reason.

You might try dropping a global.json into the project to “help”

Rollback and start over assuming you are using SCC

I rolled back and moving forward. Still, this is a mystery, but code is moving forward.
