Don't worry. Not everyone knows it...

Recently I get a chance for a code walk through of an WPF application in order to achieve better performance. So, during my review process, I came across this below code snippet:   <WrapPanel>         <TextBlock Text="{Binding Path=FirstName,Mode=OneWay}"/>         <TextBlock Text=" "/>         <TextBlock Text="{Binding Path=LastName,Mode=OneWay}"/>     </WrapPanel> If you will closely analyze this given snippet, you will definitely get a way to optimize it. Well, I am talking  about formatting the string as well as binding part. As most of you are aware that we have a property named StringFormat since .Net 3.5 SP1. So, why can't we use this StringFormat for our binding too. If you want to change the above code to incorporate StringFormat , then it will something look like: <WrapPanel>         <TextBlock>     ...
