In this post we will leverage the .NET Channels to implement reusable and composable building block functions to define a concurrent workflow.
In this blogpost example, we are implementing a Pipeline to process a set of images read from the local filesystem. The idea is to create few reusable building blocks that use Channels as an underlying way to implement a high-performant procedures/consumers pattern, and then to use these building blocks to combine the image processing pipeline. In addition, we will apply a “pipeline” higher-order function to these building blocks, which shares the same output type, in order to ease the composition of multip
