Question

I made a bit of a namespace spelling mistake and I wish to correct it. My application currently uses Application.Settings to store a bulk of the user s information. If I refactor my namespace to be spelled correctly, will the application settings file essentially get wiped because it can t find the new namespace in it?

Answer 1

I believe that ClickOnce will see this as a different application, so yes, the application settings would be "lost". I had to do this once myself, and I lost all the settings. Users had to install it as a new application and set up their personal inf all over again.

I never gt a definitive answer on why this was, but here s my guess:

If ClickOnce behaved otherwise, it would be too easy for someone to replace your app with a malicious one of their own, so from a security perspective, this makes sense.

However, I could be wrong. You could try it, and see. If the settings are lost, you can always revert (assuming you re using source control).

Answer 2

I ve never tried this before, but it looks like you should be able to just change the app.exe.config filename to your app s new name and it will read it just fine, assuming you can script that into your deployment.
