Developing CE Drivers and Applications 2-5
Microsoft Embedded Visual C++ 4.x is available without charge,
except for a nominal shipping and handling charge. Accordingly, it is
a highly economical tool for developers of CE application programs.
Device driver developers should also consider installing Microsoft
Windows CE Platform Builder 4.1, which has extensive support for
kernel level CE development that is not found in the other toolkits.
However, Platform Builder is not necessary for most driver
development work.
