Find out why C# Visual studio project doesn't update the local database

Job ID: 35610612

Budget: $10 – $30 USD

I have a simple app that uses a local database, table adapters, Dataset.
I am not supposed to use any inline SQL connection or SQL commands, Instead, I added queries to the table adapter itself.
However, when I run the app and insert a new user it gets inserted to the adapter and I can login using the info. But it doesn't update the actual database and when I close the app and run it again I cannot login with it anymore.
