Critical issue using EF Core on UWP (unable to open database file)

Steps to reproduce

Follow this simple tutorial.

The issue

Start the app either in Debug or Release.

An exception occurs with db.Database.Migrate();.

Exception thrown: 'Microsoft.Data.Sqlite.SqliteException' in Microsoft.Data.Sqlite.dll. Additional information: SQLite Error 14: 'unable to open database file'.

This is the very first step, Migrate() method should create the database if there is not any yet (it also fails with db.Database.EnsureCreated()).

EF Core Sqlite version: 1.0.0

It appears that, although the first-chance exception is thrown, it doesn't actually represent a bug as EF Core handles this and continues execution normally. However, it leads to a misinterpretation (the database is created anyway).
