WPF technology that feels marginalized

Today, I went to Beijing book building. Look for the inside SQL Server 2005 T-SQL programming.

The classification here is still very good, and I soon confirmed that I did not find the book.

So I strolled around and accidentally found that in a place where the classification has nothing to do with WPF, I found several WPF books, and there were no other WPF books left and right.

After a while, I found that there were several WPF books in another place that had nothing to do with WPF.

WPF books are poor, and they are also randomly classified. It gives people a strong feeling of being marginalized.
