 # Property functions
 
-Property functions are calls to .NET methods that appear in MSBuild property definitions. Unlike tasks, property functions can be used outside of targets. Property functions are evaluated whenever the properties or items get expanded. So, for properties and items outside of any targets, property functions are evaluated before any target runs. For property groups and item groups inside targets, property functions are evaluated when the target is evaluated.
+Property functions are calls to .NET methods that appear in MSBuild property definitions. You typically use them to construct property definitions that require more complex logic.

 Without using MSBuild tasks, you can read the system time, compare strings, match regular expressions, and perform other actions in your build script. MSBuild will try to convert string to number and number to string, and make other conversions as required.
