Whitespace is not allowed after end of Markup Extension. 标记扩展符号末尾不允许有空格

When building your Silverlight project fails with the error message “Whitespace is not allowed after end of Markup Extension.”, you’ve got a blank (or more) behind a databinding expression, like here:

1 <Button Content="{StaticResource ResText_SaveButton} "/>
注意：引号前是没有空格的
