Background

This issue tracks one of the BuildCheck analyzers we would like to ship in-box with MSBuild.

Goal

Implement an analyzer with the following rule: The MSBuild task is not executed batched when the BuildInParallel parameter is true.

Notes

The intention of BuildInParallel = true is to run child builds in parallel. Batching the task, on the other hand, makes it run in a loop, one invocation at a time, which is likely not desired.
