I passed this exam which was to do with Developing Applications using .NET 3.5 for Windows forms. I found that this exam was very much like the old 2.0 .NET windows form exam. Areas that I concentrated on were all the new updates such as clickonce, security of the form applications, and using certificates.
It appeared that this study method worked well. I also did some experimentation with Mdi forms and this was also another area where some questions were asked. Be sure that you understand how 32 bit and 64 bit applications install and how they are package in respect to using msi packages.
I recommend this exam, if you have a good knowledge of developing windows based applications. I found this exam pretty easy. Probably, too much time was allowed for it.
