I'm using EF Core in a small test application and I'm trying to create the database in SQL Server 2014 Express. Initially I used Update-Database script to create it and I didn't have any issues but when I tried to do this at runtime with dbContext.Database.EnsureCreated(), it no longer worked. I have checked the credentials for the SQL user multiple times and I'm sure that both approaches use the same. If I use the Update-Database script first, then all the queries work successfully in runtime using the same credentials.
Any idea what I might be missing here?
