Value cannot be null. (Parameter 'provider')

Seeing that the other issues that had this error did not quite fill the bill, I wanted to add my two cents. I built a project that was similar to the example provided and all was well, but when I added a project that contained a reference to Microsoft.EntityFrameworkCore version 5.0.0, also tried 5.0.1, I received the error message below. What is in the EF Core 5 that is causing this problem?

Reproduce the Azure Functions host startup with Microsoft.EntityFrameworkCore 5.0.0 and 5.0.1, using the provided host.json and log output as the starting point. Investigate the reported IWebJobsBuilder.get_Services method-not-found error and the resulting null provider; done means the project starts successfully with the affected dependency versions or the compatibility requirement is documented.
