Implement new Concept Exercise: memory-pooling

[ErikSchierboom]

This issue describes how to implement the memory-pooling concept exercise for the C# track.

Getting started

Please please please read the docs before starting. Posting PRs without reading these docs will be a lot more frustrating for you during the review cycle, and exhaust Exercism's maintainers' time. So, before diving into the implementation, please read up on the following documents:

• The features of v3.
• Rationale for v3.
• What are concept exercise and how they are structured?

Please also watch the following video:

• The Anatomy of a Concept Exercise.

Goal

The goal of this exercise is to teach the student advanced aspects of the Concept of Memory Pooling in C#.

Learning objectives

• Know what memory pooling is and why it should be used.
• Know how to use the ArrayPool<T> and MemoryPool<T> classes.

Out of scope

• Discussion of profiling tools (referring to them is fine).

Concepts

This Concepts Exercise's Concepts are:

• memory-pooling: know what memory pooling is and why it should be used; know how to use the ArrayPool<T> and MemoryPool<T> classes.

Prequisites

This Concept Exercise's prerequisites Concepts are:

• memory-allocation: know the basics of how memory works in C#, including reference and value type memory and garbage collector aspects.
• generic-types: know how to work with generic types.

Resources to refer to

Hints

• ArrayPool<T> type: ArrayPool<T> reference.
• MemoryPool<T> type: MemoryPool<T> reference.

After

• ArrayPool<T> type: ArrayPool<T> reference.
• MemoryPool<T> type: MemoryPool<T> reference.
• ArrayPool in-depth: a very in-depth discussion of how to work with ArrayPools.

Representer

This exercise does not require any specific representation logic to be added to the representer.

Analyzer

This exercise does not require any specific analyzer logic to be added to the analyzer.

Implementing

To implement this exercise, please follow these instructions.
