Remarks

A class may have as many properties marked with ActivityInput attributes as are required.

Properties marked with the ActivityInput attribute must have a public set method. Also, there are some restrictions on the property types that are allowed. Valid property types include the following:

  • Fundamental types (i.e. bool, int, uint, double etc.)

  • Enumerations

  • DateTime

  • Classes with a public constructor taking a string parameter.
