Hosted Blazor Webassembly Notice

[!IMPORTANT] The Hosted Blazor WebAssembly project template was removed from the framework with the release of .NET 8 (November, 2023). The guidance in this article is only supported for .NET 7 or earlier. Hosted Blazor WebAssembly apps that are upgraded each release continue to receive product support. Alternatively, refactor the app into either a standalone Blazor WebAssembly app or a Blazor Web App.
