I was referred here by your Razor pages tutorial on line. On the page Adding Your First Page I get an error. I'm using .Net Core 3.1.201 with VS Code 1.44.1. This looks great but I've found a few differences and I come to a dead stop when trying to build the app after adding the About page. "The type or namespace name 'AboutModel' does not exist in the namespace 'Bakery.Pages' (are you missing an assembly reference?) [Bakery]".

The problem is obviously the line @model Bakery.Pages.AboutModel but, as a beginner, I have no idea how to create the missing file or reference. Can you help?
