Better MVVM with MVVM Helpers

Let's take our MVVM to the next level with some great helper libraries that can be used in any application including Xamarin, Xamarin.Forms, WPF, UWP, and more! With MVVM Helpers you are able to easily get access to property change notifications, base viewmodels, helpers utilities, and optimizations around observable collections.

Thanks, James Montemagno Great contribution, at first it seemed a bit intimidating but now I understand and it works like a charm.

These videos have been amazing James! I have been trying to get my hands on any material that could further my knowledge on the Xamarin framework and many of the videos I found are often outdated and/or the lessons hard to follow. Your content has been by far the best I have seen. It has helped me better understand the core concepts of this platform as well as shown me handy tools to help streamline the app design process. Thank you very much for putting these tutorials out there!

I like the mvvmhelper. Using prism for WPF but seems like maybe it’s overkill for what I’m doing rn.

Hi I love your videos! Is there any chance you could make a detailed series about creating mvvm app (preferably WPF) using MVVM from Windows Community Toolkit? There arent any on the internet and WCT seems like is going to be a big thing. You could also focus even more on Source Generators

I love your recent videos. Keep up the good work!

[XuanJieTan]

[charlesemge]

These are Great JM! Cant wait to finish this series. I am sure you are getting to this - Does the MVVM handle "Global Variables" ? Im struggling to find which class or page to place something like this in?

[varadareddy]

Hi, Thanks! how to make my scanner scan the barcode to the selected entry in MVVM

[saroshwadia]

Awesome Video as usual :-) Clean, to the point and easy to understand. Great Job. Have a question, How can I keep my POCO classes clean but still use INotifyPropertyChanged? Don't really want to duplicate the POCO classes. Thx

MVVMHelpers: Over 1 million (ob)served!

Thankyou for your contribution. I was wondering if you have or can direct me to an Mvvm helper library that can assist in navigation in a Wpf mvvm application? I find this very challenging, especially when it’s not such a simple UI such as button clicks, but may involve dialog boxes, or cascading views.
