I have a C# program that is using the standard ApplicationSettingsBase to save its user settings. This was working fine under .NET 3.5. And the provided Upgrade() method would properly "reload" those settings whenever a new version of my program was created.

Recently, I recompiled the program with .NET 4.0. My program's version number also increased. But, when I run this version, Upgrade() doesn't seem to to detect any previous version settings, and does not "reload" them. It starts blank.

As a test, I recompiled yet again, going back to .NET 3.5. And this time, the Upgrade() method started working again.

Is there a way to allow Upgrade() to work when switching frameworks? Is there something else I am missing? Thanks.

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
