`Could not get the reflection type for DbContext` when using `required` keyword in model

I was following along with this [API tutorial](https://learn.microsoft.com/en-us/aspnet/core/tutorials/first-web-api?view=aspnetcore-7.0&tabs=visual-studio-code#:~:text=Run%20the%20following%20command%3A) when I came upon an odd exception. It took a bit of guess-and-check testing, but I narrowed it down to only occur when the `required` keyword is added (below is the example model).

The tutorial lists the .NET 7.0 SDK in the prerequisites. From what I've found in the [documentation](https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/configure-language-version), that should use C# 11 (which is when the `required` keyword [was introduced](https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/required)). Is this an issue with the `aspnet-codegenerator` tool, the documentation, or my own misunderstanding?

Code:
``` C#
namespace TodoApi.Models;

public class TodoItem
{
public long Id { get; set; }
public required string? Name { get; set; }
public bool IsComplete { get; set; }
}
```

Stack Trace:
```
