+# Appunti gestione BlaServApp DB
+
+
+Per la gestione dell'accesso al DB si opera con EFCore --> app blazor server
+
+## Scaffolding 
+
+Per generare le classi da un DB esistente con cui operare EFCore CodeFirst usare lo scaffolding coi seguenti comandi.
+Attenzione: la classe DbCOntext viene creata INSIEME alle viste nella folder DatabaseModel (nell'esempio seguente...)
+
+### DB iniziale
+
+ Scaffold-DbContext "Server=SQL2016DEV;Database=BlaServApp;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir DatabaseModels
+
+### SOLO di tabelle/viste selezionate (con force update)
+
+Scaffold-DbContext "Server=SQL2016DEV;Database=BlaServApp;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir DatabaseModels -Tables nome_tabella, nome_vista
