The purpose of UseBlazorFrameworkFiles

[nikki9696]

Hi,
We are building a Blazor app and putting the build output into a folder that's part of a site hosted by Core/Azure.
My question is about UseBlazorFrameworkFiles - I don't know if it's because of how we're hosting the output as just static files, but we don't seem to need this call in order for the app to work. It just works fine; framework files are in the _framework folder under our app folder and seem to get served as needed. I can't find in depth details on what it's truly for. I'm wondering if we'll need it down the road once we get more complex interaction going.

Any insights?
Thanks!
