However, I am looking to submit the form on every change of any control on the form. Googling for an hour has not lead me to an answer. Does anyone have any pointers?...

✅ Migration-independent Database Seeding

Curious if EF has some sort of independent database seeding potential? I am kinda hoping to see a similar functionality to Laravel's Database Seeder where you can write the seed in a file which you can run at any time, regardless of whether or not your migrations are already ran. I find the HasData fucntiuonality inherently counterproductive as I don't want to re-run all migrations over and over just so I can work with my seed data.

DataSet, DataTable from System library doesn't generate nullable attribute.

In System. Data. Common has a DataSet, when you call api Dataset.GenerateXmlSchema(), it generates XSD file with elements and type attributes, but it doesn't add "nilable" attribute to the xml elements. Is there other ways to generate xsd file from postgreSQL Database with appropriate attributes?

✅ WPF Application, renaming

So i'm currently going through an assignment and creating the necessary classes which our WPF program should have. However i got a question... It says i should rename the initial MainWindow to GameWindow. Does that mean i rename MainWindow.xaml.cs to GameWindow.xaml.cs ? The problem is if i do that i get an error.....
