Question

I have simple application. To be more specific this is Visual Studio Addin.
Client needs to specify several settings (string, int, decimal etc)

I need to be able to load it at starup time and save if changed.

Let’s say for simplicity I have all settings in one class AppSettings.

I can of course use DataContractSerializer to serialize/deserialize AppSettings but
I think there must be some standard way.

There are Application Settings from Microsoft:

You can use it like this:

Properties.Settings.Default.DumpHeader = dumpHeader;
Properties.Settings.Default.DumpFooter = dumpFooter;

Properties.Settings.Default.Save();

And loading works similar. But you have to define a .settings file first. It’s from the WPF Framework, not sure if it works for WinForms too.
