CodeDomSerializ er and Asp.Net custom control

[onyxring]

I've been building custom web controls in C# with VS2005. Currently I'm
looking into adding design-time functionality and have reached a point where
I need to generate code in the page the custom control is on. Enter the
CodeDomSerializ er class.

I've found several examples creating Designer Serializers, nearly all of
them for windows forms, but a few claiming to work for Web Controls;
however, I have been singularly unsuccessful at every attempt to modify
source code during the design-time experience. Clearly I'm doing something
wrong, but what it is escapes me.

Below is a sample of the technique I've been using, scaled down to the
barest minimum and excluding designers and other things you might expect for
a custom control. It appears to me that this should work, though adding this
"newtest" control to a page clearly does not add the comment expected.

Can anyone add some clarity at to what I'm doing wrong? Thank you in
advance.
