Na sexta eu estava conseguindo rodar bem a lista de produtos, mas hoje tudo que envolve o banco está dando o seguinte erro:
System.Data.Entity.Core.ProviderIncompatibleException: 'An error occurred accessing the database. This usually means that the connection to the database failed. Check that the connection string is correct and that the appropriate DbContext constructor is being used to specify it or find it in the application's config file. See http://go.microsoft.com/fwlink/?LinkId=386386 for information on DbContext and connections. See the inner exception for details of the failure.'
