DataContext in Xamarin And WPF

[KurdCsharper]

Summary

We can use Window.DataContext in WPF to specify the ViewModel.

as a friend mentioned in a comment, Xamarin has this feature too, but with a different syntax.
I'm WPF Developer and I think it's not a good idea to have two syntaxes for XAML.

API Changes

This is how it works in WPF.

<Window.DataContext> <vm:PurchasePaymentViewModel x:Name="viewModel" /> </Window.DataContext>

And the Same Property for Xamarin with Different Syntax
<Window.BindingContext> <vm:PurchasePaymentViewModel x:Name="viewModel" /> </Window.BindingContext>

I'm WPF developer and the first time I code Xamarin, I said home sweet home, Xaml Again 💯
But there are some differences and I don't know why

If you set the x:DataType on the Page to your ViewModel, it currently gives you Intellisense and many more! Take a look at Compiled bindings - https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/data-binding/compiled-bindings

yea that's right.
I'm WPF Developer and I'm new to Xamarin, so I look forward to DataContext instead of BindingContext.
having two Xaml Syntax is not a good idea.
They need to use same syntax as WPF.

@KurdCsharper I faced the same dilemma when I started out in Xamarin 4 years ago. Then I just accepted the fact that things were different between WPF and Xamarin, but I asked the same question back then only to realize my opinion meant nothing. Now when I start to write WPF, I start writing XAML like it's Xamarin, I find out it doesn't build, and I have to teach myself WPF all over again. lol

Don't worry. Xamarin is changing into MAUI. 2 years from now, it will be something else. Maybe we'll write mobile apps in HTML and not XAML. The only thing permanent is change in the world of technology.

Yea but I like Xaml. and I hope they use the same XAML as WPF.
