If you have a Blazor application you can include it on your .NET Aspire solution and add the ".NET Aspire Orchestrator Support" - make sure your Blazor app and packages are updated to .NET 8, beyond that you also might need to do some extra configuration. I suggest you to take a look at the Blazor application that is created in the .NET Aspire template and see how it is configured. If you have a JavaScript app, it's still possible but needs some extra effort (at least until now), perhaps this PR on the Aspire repo might be interesting for you: https://github.com/dotnet/aspire/pull/1033.
