Gulp is an easy-to learn, easy-to-use JavaScript task runner that has become an industry standard. This book offers an entry to Gulp for experienced developers. Author Kris van der Mast offers practical examples and clear descriptions, making Gulp Succinctly the perfect entry point for developers interested in Gulp. 

There are various techniques that could be implemented to achieve asynchronous interactions among microservices. In this article, I shall talk about a use case where we would be using a message broker – RabbitMQ – and “Fanout” technique to implement the asynchronous messaging pattern in action.

At Build 2019, Microsoft announced the release date for .NET Core 3.0 to be this coming September. This release includes the highly touted support for desktop platforms like WinForms and WPF. Today, there’s still a large developer base that’s building desktop applications using these .NET Windows desktop frameworks and by using .NET Core 3.0, you can now build desktop applications on the .NET Core platform.
