FeatureCost Property

[This is preliminary documentation and subject to change.]

This is the FeatureCost property of the MsiEngine object. This property returns the total amount of disk space (in units of 512 bytes) required by the specified feature and that of all the feature's parent features (up to the root of the Feature table). For each feature, the total cost is made up of the disk costs attributed to every component linked to the feature.
