It's somewhat early days, but workable. The search term you probably want is "Blazor Desktop". It's basically Blazor Server but served to a local webview instead of a remote client. .NET 6 will have some convenient ways to do this in WinForms, WPF, and MAUI. But if you're willing to go off the beaten path a bit, it's not too hard to assemble the bits on your own (serve up Blazor on a background thread, consume it in your web view control of choice).
