What is the Markup extensions in XAML?

Question

when and why we use curly braces ( { and } ) to provide the value of an attribute syntax in XAML?

Satyapriya Nayak · Answer

Hi Shubham When used to provide the value of an attribute syntax curly braces ( { and } ) indicate a markup extension usage. This usage directs the XAML processing to escape from the general treatment of attribute values as either a literal string or a string-convertible value.
