x:Bind vs TemplateBinding inside ControlTemplate

Question

https://learn.microsoft.com/en-us/windows/uwp/xaml-platform/templatebinding-markup-extension#xbind-in-controltemplate

What is the difference between using TemplateBinding and x:Bind inside the ControlTemplate? On the document, it is mentioned that Function Binding and Twoway binding can be done through x:Bind. But is there any internal info that TemplateBinding is more lightweight than x:Bind? Is TemplateBinding better than x:Bind in terms of performance?

Hello @guess_me_if_u_can,

It's preferable to use {TemplateBinding} when {TemplateBinding} is capable of covering your requirement, Linking the value of a property in a control template to the value of some other exposed property on the templated control. And also note

Using x:Bind in a ControlTemplate requires Windows 10, version 1809 (SDK 17763) or later. For more info about target versions, see Version adaptive code.

If you really care about the performance under different conditions, you can consult it at https://github.com/microsoft/microsoft-ui-xaml/issues.
