XmlSerializer serializes class with primitive elements pretty good, but for some reason
it does not serilize Color despite the fact that Color is a structure.
Is it bug or feature? Is there a workaround or something?

I assume you mean XmlSerialize in DotNet.
As far as I understood, XmlSerializer can work only with public read/write properties.
In Color R,G,B and A in Color are read-only, so serializer cannot restore them from XML file.
In fact, XmlSerialize does not even try to save them.
You have 3 options.
1. Use KnownColor instead of Color.
2. If you have non-standard colors, save R,G,B and A for every color or make your own structure
with public R,G,B and A.
3. Write custom serialization function.

oops, I mean
Thanks a lot!
BTW, Rectangle looks in XML like
<Rectangle>
<Location><X>5</X><Y>5</Y></Location>
<Size><Width>40</Width><Height>40</Height>
</Size>
<X>5</X>
<Y>5</Y>
<Width>40</Width>
<Height>40</Height>
</Rectangle>

Look at Rectangle structure.
It has following public properties with read/write access:

X,Y,Width,Height,Location,Size
It is exactly what you see in the XML

Location and Size is just duplicate of X,Y,Width,Height

It seems, the DotNet 1.1 XmlSerialize I use, reads X,Y,Width,Height
and ignores Location and Size

If you prepare XML file manually, you can remove Location and Size.
If you save and load XML file with XmlSerialize, why would you care
as long as it works properly?
