@Pexers-0532 ,
Thanks for reaching out to Q&A.
The contents in the zip file should be dlls and not the entire content of the source code ( I can see the localsettings.json and the entier src folder). It appears that the build step is missing. Make sure you build the function app and then deploy to the Azure functions runtime.
