Visual Studio 2005 doesn't have a WinCE5.0 SDK. It ships with PocketPC 2003 SE and SmartPhone 2003 SE images. You can install corresponding WindowsMobile 5.0 PocketPC and WindowsMobile 5.0 Smartphone SDKs from web as free download. Although Device Emulator BSP (Emulator used with Visual Studio 2005) is available for download http://www.microsoft.com/downloads/details.aspx FamilyID=474B03A6-E87D-455D-BC16-B8CF18EF39B4&displaylang=en and you can roll your custom image and use it with Visual Studio 2005 (See this link for instructions on how to do this http://blogs.msdn.com/barrybo/archive/2006/08/21/710908.aspx).
