Reactive Programming for .NET Developers

Overview of this book

Reactive programming is an innovative programming paradigm focused on time-based problem solving. It makes your programs better-performing, easier to scale, and more reliable. Want to create fast-running applications to handle complex logics and huge datasets for financial and big-data challenges? Then you have picked up the right book! Starting with the principles of reactive programming and unveiling the power of the pull-programming world, this book is your one-stop solution to get a deep practical understanding of reactive programming techniques. You will gradually learn all about reactive extensions, programming, testing, and debugging observable sequence, and integrating events from CLR data-at-rest or events. Finally, you will dive into advanced techniques such as manipulating time in data-flow, customizing operators and providers, and exploring functional reactive programming. By the end of the book, you'll know how to apply reactive programming to solve complex problems and build efficient programs with reactive user interfaces.

Preface

Chapter 9. Advanced FRP and Best Practices

In the previous chapter, we introduced a 360-degree description of FRP. We discussed the main features related to this type of programming, passing from a theoretical introduction to the concrete examples of the scenarios. We also described how the Event module of the F# language exposes functionalities to manage the Event type delegate in the .NET Framework and how this module amplifies its capabilities, adding also a set of functionalities to manage events, such as collection (the IObservable interface). Finally, we conclude the chapter showing the main differences between push-based and pull-based scenarios.

FRP is not a simple subject to understand; in fact, it is frequently considered very difficult to assimilate. This problem depends on the complexity of the concepts; anyway, once you understand their meaning, it is not so straightforward to put them into practice. In other words, the only relatively simple aspect is the presence of objects...
