Blazor Teams App - Azure SQL / EF Core

Hello,

I'm new at developing Teams app with the FX SDK. I started out with a predefined template for a Blazor Tab app. 

I will deploy it ti Azure and I want to use Az SQL as database.

But I cannot find in the docs nothing related to how to integrate EF Core or how to setup a connection to a SQL Server instance.

Does anyone have a guide or some documentation links that I couldnt find, please?

Thanks a bunch!
