# The new project system does not support designers. This blocks our ability to make XAML
# changes through the designer. A rare event but necessary on occasiona.
#
# This script helps with the times where XAML changes are needed. It will temporarily revert
# the projects which have XAML files to the legacy project system. The XAML edits can then
# be processed and the coversion can be reverted.
