Gets or sets the path to a Double value on the source task item to serve as the task cost, or null to indicate that the cost is not provided by the source task item. Task cost can be computed automatically based on duration and assignments. The cost of a parent task will be based on the cost values of its children. However a specific task cost can be set and will be used instead if it is higher than the automatically computed cost. This is a dependency property.
