So after updating all the Nuget packages with the latest Azure SDK's and doing another publish, the issue seems to be resolved.
Azure Function suddenly getting Entry Point was not found error

We currently have a deployed Azure function, created with Visual Studio, that now all of a sudden starts returning an exception on calling the HTTP function of "Entry Point was not found". The worst part is that the local Azure function runs fine making debugging a nightmare. Has anybody gotten this problem and possibly a fix? The Function.json file has a endpoint assigned on Azure portal.
