When creating a Blazor application, in what cases would I select "ASP.NET Core hosted"?

Question

Here's the prompt that I see in Visual Studio:

In what cases should I check the box that says "ASP.NET Core hosted"?

I would like to follow the client-side model here (no SignalR), and my intent is to right-click-publish to an Azure App Service.

Answer 1

... to right-click-publish to an Azure App Service.

Means you want to use a service (providing an API backend).

In that case the "Hosted" template is the ideal starter kit. It essentially is two projects in one: an independent SPA application and an API Service.

But do note that you could develop those two independently as well.

When you don't need/want a service then simply don't check the "Hosted" option. And then there is no need for an App service to deploy to.
