A new release of the Windows Marketplace for Mobile requirements went live today. Many developers should be happy with change in the PNG Start screen icon requirements. Prior to today, you were required to include three PNG files (one for each possible DPI) in your installation CAB file. Today, this requirement is one (90×90) icon.
The three icon requirement, necessitated a setup DLL to dynamically copy the appropriate PNG according to the device DPI. Now the setup is much easier – only requiring CAB file definitions and no C++ code.
