| 1. We should disable the `EnsureLatest` bundles setting from the host. We should not need this if we | ||
| do the bundles management on the core tools side. | ||
| 2. We should not download bundles for stacks that do not require it (e.g. dotnet apps) |

There was a problem hiding this comment.
dotnet in-proc scripting apps will need bundle.
Another consideration, if user just has http or timer trigger functions in their function app, bundle is not required to run the app. This can only be determined for apps with host based indexing or customer's can remove it themselves.
Only need for bundle in such case would be templates

Design proposal for offline support in Core Tools.
One of the major issues is that today we require internet connectivity to download extension bundles from
cdn.functions.azure.comduringfunc start, causing local development to fail in offline. This design proposes making the tool fully functional offline by implementing cache-first fallbacks for all network operations while maintaining optimal online performance.
