Extension Methods Guidelines in C# .NET
Extension methods are an excellent feature of the C# language. They enable us to write nicer, more readable code. They allow for more functionally styled programming, which is very much needed in an object-oriented language. They also should be used with care. Inappropriate use of extension methods can create less readable code, make it harder to test and even be prone to errors.

I have 5+ years of experience in .NET, developing in Xamarin Forms since it started (in 2014). Currently Xamarin Certified Developer and Microsoft MVP. In my free time, I write articles in my blog Xamgirl.com
Tell us one thing we probably don't know about you?
Before becoming a developer I was a musician, I used to play the trumpet :P.

A project about AI + Xamarin Forms, was great because I learned a lot of new stuff. (Sadly, cannot talk much about it. NDA :P).

The Xamarin community is awesome, so don't be afraid to ask questions, you will always find someone willing to help. Also, you can check this guide I wrote a few months ago with some tips to learn Xamarin: https://xamgirl.com/learning-xamarin-forms-personal-recipe/
What are the MUST HAVE tools, resources and libraries that you use when building Xamarin apps?
Where do you think mobile will be in 5 years?
