BindingOperations Missing #23089

Open bobbydharrell opened 2 weeks ago

bobbydharrell commented 2 weeks ago

Description

While trying to work in an attached behavior I discovered that the UIElement was losing the binding context with what I was doing. In an effort to fix this I tried to retrieve the Binding to preserve it, but found that BindingOperations and BindingExpressions were not in .Nat MAUI. Please port them over.

Steps to Reproduce

No Demo is needed as it is just a missing feature

Verified this issue with Visual Studio 17.11.0 Preview 2.1, Can repro it. MAUI project prompts you to install the Uno.UI package, but WPF project works fine. WPF: image MAUI: image
