Hi all, I have a .NET 3.5 class library I built that reads an App.config file for values it needs. It can pull the config values just fine when I test it in Visual Studio.

E.g. string[] a = { "a", "b", ... }; string max = a.Max(); What locale is used here - current, invariant? How can I affect it? The comparision seems to be case-insensitive, what if I want to find case...
I have a small UserControl and it needs to know the Background Brush of the control on which it's being rendered. However, if I look in the Background property of the UserControl it comes back null.

Are Select and SelectMany preferrable to Joins? The reason I'm wondering is because I use LinqPad and in one section there are comments that say: // Note: before delving into this section, make sure you've read the preceding two // sections: Select and SelectMany.
