This is shorthand for binding to the current source. For more info see here.
这是绑定到当前源的简写。有关更多信息，请参见此处。
From the documentation specifically:
具体来自文档：
Optionally, a period (.) path can be used to bind to the current source. For example,
Text="{Binding}"is equivalent toText="{Binding Path=.}".
可选地，可以使用句点 (.) 路径绑定到当前源。例如，
Text="{Binding}"相当于Text="{Binding Path=.}"。
