[Question] (C# compiled functions) Some functions when deployed to azure seem to need the webapp restarted before picking up changes

Hi, more a question as I haven't found anything obvious in the docs and I see this happen every now and then...

(This is a C# Compiled function app using the preview VS tooling. Being deployed by a VSTS deployment agent using the webapp package upload. Running on a Consumption Plan).

Sometimes, more noticeably when adding a new function, it may not be accessible after the deployment has finished. If I navigate to the functionApp on azure, I see the function in the list. When I click on the name I get an error that includes "The function type name 'XYZ' is invalid.", but still lists the json describing the function, etc.

If I restart the functionApp and go back to it - all good.

Q) Is there a delay between the deployment and the running function detecting that the files have actually changed?

Has anyone else seen this before?

Thanks,
