In my new project, which I'm developing with WPF in .NET 10, I'm having trouble using the PasswordBox in a user authentication window. In my code, I've used the PasswordBox's KeyDown and PreviewKeyDown events. Normally, when a user enters their password and presses Enter, if the password is correct, DialogResult is set to true and the Close() method is called. And it's at this point that the program stops, when DialogResult is set to true. The program crashes without returning an error message. However, in a previous project I developed with WPF in .NET Framework, I didn't encounter this problem. Despite my research, I haven't found a solution. The good news is that when the validation button is clicked after entering the password, the window closes without any problem. Pressing Enter when the PasswordBox has focus causes a problem. Please, I need to understand how to fix this bug.

Hi everyone, I’m coming from a Windows Forms background where I used EDMX (Entity Data Model) to map my SQL Server database. I really liked how I could easily update the model from the database and get all the fields ready to use in my code whenever the DB structure changed. Now I’m moving to WPF, and I’d like to keep the same convenience — meaning, if I modify the database, I want to be able to update a data model (like EDMX) so that my entities and properties stay in sync automatically. I’d like to keep using Entity Framework and SQL Server, but I’m not sure what’s the best approach in WPF for this scenario. Any suggestions or modern alternatives to EDMX that would work well in WPF? Thanks in advance for your help!
