What is the location of your database? Make sure you are not you're copying it to your output directory everytime you run your code. I might have had a similar issue with an SQLite database which was copied to the output directory every time I run my application, which made me lose changes I had made during the previous run

First of all, SaveChanges(true) is an obsolete method so I wouldn't recommend using it. Have you tried just using SaveChanges() ? Like in db.SaveChanges()

The closest method to SaveChanges(boolean) is SaveChanges(SaveOptions) which Persists all updates to the data source with the specified SaveOptions.

I strongly recommend you to (if at all possible) to modify your entity so the setters are private (don't worry, EF can still set them on proxy creation), mark the default constructor as protected (EF can still do lazy loading/proxy creation), and make the only public constructors available check the arguments....This has several benefits:...You lim...
