About Gerald Versluis

I'm a full-stack software developer and Microsoft MVP from The Netherlands. After years of experience working with Xamarin, Azure and other .NET technologies, I have been involved in numerous different projects and realised several apps.

Not only do I like to code, but I am also passionate about spreading my knowledge - as well as gaining some in the bargain. I involve myself in speaking, providing training sessions and writing blogs (https://blog.verslu.is) or articles in my free time.

$31.25

Learn everything you need to set up a full-featured, automated pipeline for Xamarin development and deployment. Automate everything from the build step through to deployment and delivery to your customer. If you thought this level of automation could be achieved only by large companies with generous funding, think again! You as a single developer, or working in a small team or company, can automate your processes to punch heavier than your weight. What’s more, you can achieve this level of automation completely for free!
This hands-on guide takes you step-by-step from setting up your first automated build all the way to integrated unit testing, and finally through to delivering a high-quality app to your testers and end users.

Not only does this book teach how to get a grip on consistent quality, but it covers the use of HockeyApp to track events and usage, and to report errors and anomalies back to home base for developers to investigate. Many times it’s possible to detect and fix errors before a user even notices they are there.
