Firstly, .NET MAUI 9 Preview 5 has just been released. The changelog can be found here. Notably, a new Blazor Hybrid Web template has been introduced in this version.
In short, this new template abstracts the Razor components into a distinct Razor Class Library (RCL). Furthermore, it provides the ability to create Blazor Web projects within the same solution and refers to the shared RCL.
The concept of abstracting the Razor components is already facilitated by the Hybrid project templates within the All-in-One template pack.
