Summary

This chapter explained what you can expect from and how to code LINQ queries that support multi-core processors and multiple CPU machines. This has always been possible, but the complexity caused difficult-to-debug programs and hard-to-find bugs. Parallel LINQ makes coding queries that support parallelism both easier and more predictable.

Writing your own parallel operators is no more difficult than writing a good sequential operator (when building on top of existing operators), and when a programming task is going to operate on large collection sizes of data, an investment in time is worth making.
