Colophon

.NET Framework Essentials is a concise and technical overview of the new Microsoft .NET Framework.
Covered here are all of the most important topics—from the underlying Common Language Runtime
(CLR) to its speci alized packages for ASP.NET, Web Forms, Windows Forms, XML and data access
(ADO.NET). The authors survey each of the major .NET languages, including VB.NET, C# and
Managed C++.

Colophon
Our look is the result of reader comments, our own experimentation, and feedback from distribution
channels. Distinctive covers complement our distinctive approach to technical topics, b reathing
personality and life into potentially dry subjects.
The animals on the cover of .NET Framework Essentials are shrimp. The 2,000 species of shrimp
range in size from fractions of an inch to 8 inches-with an average size of about 4 inches. Like other
crustaceans (including lobsters, crabs, crayfish, and barnacles), the shrimp has a segmented body
covered by a hard, translucent exoskeleton, has a flexible abdomen and fan-shaped tail, and utilizes a
"toolkit" of jointed appendages-each with specialized functions for various activities. The shrimp's
exoskeleton, while providing a strong protective layer over its body, must be shed occasionally to allow
for growth in a process called molting. Similar to this process of regrowth, lost appendages can be
regenerated if need be.
Different species of shrimp are found in marine and fresh water--shallow and deep--all over the world.
Swimming backward by rapidly flexing its abdomen and tail, and with the assistance of specialized
legs for swimming, the shrimp feeds on smaller plants and animals, as well as carrion. In fact, several
species engage in symbiotic (mutually benefical or dependent) relationships with other organisms. The
coral shrimp (Stenopus hispidus) cleans the scales of the coral fish, while the fish in turn swims
backward through the shrimp's pincers (presumably to clean them). In addition, species of Alpheus
shrimp share burrows with blind goby fish. The shrimp brings food to the goby, while the goby cleans
the burrow and warns the shrimp of danger by using signaled body movements.
Interestingly, certain species of shrimp are hermaphroditic. The juvenile shrimp grows up as a male
and is fully functional in sexual reproduction with females. When it reaches half the size of the female,
the male shrimp loses its male sexual organs and develops those of the female. Upon reaching full
size, the shrimp is then a typical female and is fully able to mate again. However, this time it mates
with a juvenile male, rather than with an adult female as before.
Jeffrey Holcomb was the production editor and copyeditor for .NET Framework Essentials. Mary Brady
and Claire Cloutier provided quality control. Sada Preisch and Edie Shapiro provided production
assistance. Joe Wizda wrote the index.
Ellie Volckhausen designed the cover of this book, based on a series design by Edie Freedman. The
cover image is a 19th-century engraving from the Dover Pictorial Archive. Emma Colby produced the

cover layout with Quark™XPress 4.1 using Adobe's ITC Garamond font.
David Futato designed the interior layout based on a series design by Nancy Priest. Anne-Marie
Vaduva converted the files from Microsoft Word to FrameMaker 5.5.6 using tools created by Mike
Sierra. The text and heading fonts are ITC Garamond Light and Garamond Book; the code font is
Constant Willison. The illustrations that appear in the book were produced by Robert Romano and
Jessamyn Read using Macromedia FreeHand 9 and Adobe Photoshop 6. This colophon was written
by Jeffrey Holcomb.
