Issue when connecting to azure sql over Virtual Network in App Service.

Describe the bug

• I can connect with the user via SSMS.

• If I run the code locally on my machine it works.

• If I run it in an azure app service using IP whitelisting against azure sql it works.

• If I use Virtual Network with the app service for whitelisting the virtual network against azure sql it no longer works.

I use the virtual network method with other apps that do not use entity framework core.

I am working on implementing this sample.
