[Xamarin Forms] build error: Unable to cast object of type 'Xamarin.Forms.Xaml.ElementNode' to type 'Xamarin.Forms.Xaml.ValueNode'

Xaml build error

For one of my Xamarin project, I just had this build error:
This error was related to my XAML code:

Unable to cast object of type 'Xamarin.Forms.Xaml.ElementNode' to type 'Xamarin.Forms.Xaml.ValueNode'

After searching for a long 'moment', I just didn't understand what happened...



My investigation (this process can help you :p)

So I decided to remove a large part of my xaml code and then re-add it little by little. Each step I tried to compile to see when error occurs.

So In my case, I determined that the piece of code that was going wrong was the following:



Ok, it was my mistake but in the code editor, Visual Studio didn't tell me anything.
I was trying to bind an event (I though it was a property) to a DateTime property... What is not possible.

Hope this helps someone to save a few minutes :)

    This did help me with a similar error with a ListView. I was binding to ItemSelected instead of SelectedItem.
    Thanks for this!

EMGU with Xamarin Forms guide [part 1]

I- Introduction, OpenCV and EMGU Do you know OpenCV ( Open Source Computer Vision Library:  https://opencv.org/ ) ?  This open source library let's you work and play with images and videos with a lot of powerful image processing algorithms !  If you want some details, I suggest you to first navigate to the link above or search for 'OpenCV' on Google.  Examples of OpenCV processing found on the web (filters, object detection, edges...): EMGU is a .NET OpenCV wrapper. That means that you will be able to use OpenCV functionnalities in your .NET projects using C# for instance. EMGU is cross platform, so you will also be able to use it in your Xamarin projects ! That's great because there is no advanced image processing library in Xamarin. In this article, we will talk about EMGU and list the steps to setup a Xamarin Forms project using EMGU . It may help you because, we must say that it's not a trivial task...  II-What do I need...

Discover 'FFLoadingImage' library Today I want to make a quick presentation of a really good library for Xamarin Forms . This is the kind of library we would like to see more often on XF... This one is dedicated to image manipulation. It's called " FFImageLoading ". If I take time to make this presentation, it's because I think that we should use it in almost all our "basic" Xamarin Forms applications. When I say basic, I exclude Games or other specific apps. But in my mind, I suggest you to change all your traditional "<Image />" by "<FF:CachedImage />" in your apps. Before to start, where to find it ? On Github:  https://github.com/luberda-molinet/FFImageLoading On Nuget:  https://www.nuget.org/packages/Xamarin.FFImageLoading Main features So what will you find using this library ? I will not explain all the details but the main interesting features of the library. Multi-platform The good po...
