The document discusses task batching in MSBuild, where tasks are grouped and executed together based on metadata, and target batching, where targets are executed once per batch based on output attributes. It also covers incremental building in MSBuild, where targets are skipped if their inputs and outputs are up-to-date.

Target Baching
 Target
batching is driven entirely by the
Outputs attribute of the target. Based on
the batches created, the target is
executed once per batch.

Incremental Building
 MSBuild
checks if the inputs and outputs of
a target are up-to-date before it runs the
target.
 Both inputs and outputs are up-todate, the target is skipped.
