This blog post was written with Windows CE 5.0 in mind. In Windows CE 6.0 the sources file has changed, so you'll have to clone and change the sources file accordingly but not copy it straight from the blog post.
In short; you'll have to make sure the TARGETNAME is set to SDBUS2 to get an output of SDBUS2.DLL.
