.Net Replacement for CodeMax (Embedded Code Editor Component for COM)

Hi All, I used CodeMax for many years as a VBScript code editor, syntax highlighter and intellisense. However, it does not look like it is being updated anymore.

Is xaml in WPF equivalent of .Designer.cs in Windows Forms apps?

Is xaml in WPF equivalent of .Designer.cs in Windows Forms apps? Does it just provide compile-time state for the UI? I am not sure but it looks like you can do things programmatically with xaml at run-time. If I have a basic UI state where everything is added at run-time, then should I be looking outside the xaml stuff? ...

Is there a generic alternative to the ListDictionary class?

I was looking at some sample code and in it they used a ListDictionary object to store a small amount of data (around 5-10 objects or so, but this numerber could change over time).

C#: How to implement IOrderedEnumerable<T>

I want to implement some various algorithms for practice, just to see how bad I really am and to get better :p Anyways, I thought I would try to use IEnumerable<T> and IOrderedEnumerable<T> and other .Net collection types just to be compatible (so that what I write can be used more easily later). But I can't find a way to return an ins...
