Question

What is the best way to store user settings for a .NET application?

Hello. What is the best way to store application settings in .Net 4.0? Windows Registry? Application.Settings?

What if I want to be able to update program and keep settings from older version (New version can have more new setting and some old ones deleted)?

What if I want to store collection of my custom objects?

I know there is similar question but it's about .Net 2.0. Maybe there are some new ways of saving settings in 4.0.

Thank you in advance.

I don't think .NET 4 added anything new with regard to application settings.

See this for what's new in .Net 4. http://msdn.microsoft.com/en-us/library/ms171868.aspx
