Twoway binding in wasm - uno-platform

Question

I'm testing the Uno platform and wasm.
I test a simple databinding where I have a username in a textbox after login ainst a webapi I update the property of the username to test the update of the gui from a binded property in the viewmodel.
xaml.
in the login button
var result = await webApiClient.LoginUser(ViewModel.LoginModel);
ViewModel.LoginModel.Email = result.Model.Name;
If I run the app under UWP it works, under wasm the text box don't update.

Answer 1

{x:Bind Mode=TwoWay} is not supported right now on Uno.
https://github.com/unoplatform/uno/issues/2587
You can, instead, write it this way as a work-around:
Text="{Binding LoginModel.Email, Mode=TwoWay, RelativeSource={RelativeSource Self}}"
