### Describe the bug

I made a brand new .NET 6 project with VS22, I added Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation package (version 6.0.1) from NuGet to the project, then I have added in the Program.cs:

`var builder = WebApplication.CreateBuilder(args); `
`builder.Services.AddControllersWithViews().AddRazorRuntimeCompilation();`
