In previous versions of CodeSmith Generator prior to CodeSmith Generator 4.0. CodeSmith Generator stored property settings in an Xml document. An entirely new format was built to replace the existing format; the new format is named CodeSmith Generator Project file. It has many improvements and capabilities over the previous format. A command line option was built to upgrade existing stored Xml Property Settings to the new format.
To upgrade to the new format, please launch command prompt and type in cs.exe mypropertyset.xml /upgrade:mynewcsp.csp
