Create the Aspire Starter App with `dotnet new aspire-starter --use-redis-cache --name AspireApp --output AspireApp -f net11.0`, then run `dotnet run` from `AspireApp/AspireApp.AppHost`. Start by inspecting the `webfrontend` resource output and the attached log, comparing behavior with the .NET 10 version and with Redis disabled. Done means the Redis-enabled .NET 11 starter app starts its webfrontend successfully.
