Current behavior

The following expression does not build properly:

Published.ToString('MMM d', {x:Null})

Workaround

Use this instead:

Text="{x:Bind sys:String.Format('{0:MMM d}', Published)}"

Environment

Nuget Package Version(s): 3.6-dev

Note to contributors

The support for this type of conversion is located here:

uno/src/SourceGenerators/Uno.UI.SourceGenerators/XamlGenerator/Utils/XBindExpressionParser.cs

Line 34 in 6db4ebd
