Xaml binding expression markup validation is not strong enough about uno

[Henk7]

@MartinZikmund yes

@Henk7 Looks like Bindings need more markup validation, I'll adjust the issue title accordingly.

Thanks !

I've tried to reproduce this as follows:

<Page
    x:Class="App8.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:App8"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:mynamespace="using:Windows.UI.Xaml.Controls"
    xmlns:shared="using:TestNamespace"
    mc:Ignorable="d">

    <StackPanel>
        <mynamespace:Button Height="200" Width="200">
            <mynamespace:Button.Template>
                <ControlTemplate TargetType="mynamespace:Button">
                    <Ellipse Height="{TemplateBinding mynamespace:Button.Height}"
                             Width="{TemplateBinding mynamespace:Button.Width}"
                             Fill="LightBlue" />
                </ControlTemplate>
            </mynamespace:Button.Template>
        </mynamespace:Button>
    </StackPanel>
</Page>

But it works without the parenthesis. Anything I'm missing?

There were some improvements with this issue, the parser now reports more detailed errors.

@Henk7 can we close this one now?
