Deploy to web app does not working for .NET 8 and Linux based deployment - azure/webapps-deploy@v3 about webapps-deploy

Just to come back to this as i now know why its broken and how to fix it.

Since the latest .net 8 functions, they have changed how the compiled output works and they now create an ".azurefunctions" folder which holds the functions and references inside it. Whats really important about this is by default most compression libraries out there actually don't defaulty include folders that start with a "." in their name as in normal context, these folders are reserved for hidden directories. This means if most peoples CICD are ziping the release build up and then deploying it using webbapps, unless you override the default zipping logic, the ".azurefunctions" folder will not be zipped up along with your build and it will suddenly wipe all your azure functions upon a deployment as its missing the files required.

To fix this, when the zipping process occurs you will need to specifically specify to include the ".azurefunctions" directory, this will force the compression library to include it regardless of the fact that it starts with a "." in its name and it will solve the problem.

Hope this helps someone who comes across this.

We are having the same issue since upgrading to NET 8 for our function apps. After deploying via the CICD it simply wipes the app plan for some reason.
