We have shipped our final Fidalgo CTP release under a new name. The new name is "Visual Studio 2005 extensions for .NET Framework 3.0 (WCF & WPF), November 2006 CTP" This new download of Fidalgo works against the RTM of the .NET Framework 3.0. It will not install against any previous versions of the Framework. The .NET Framework 3.0 RTM is a prerequisite as is the Windows Vista SDK and Visual Studio 2005. You can pick up a copy of this last release at http://www.microsoft.com/downloads/details.aspx?FamilyID=f54f5537-cc86-4bf5-ae44-f5a1e805680d&DisplayLang=en.
This release wraps up the last bug fixes we will address in this series of CTPs for this technologies. It comes under a new name to help understand how to choose between Fidalgo and Orcas. This last release also ships the final CTP of the WPF Designer currently codenamed Cider.
Going forward the future CTPs of Visual Studio codenamed Orcas will integrate the technology available today in Fidalgo. You will find going forward that Orcas will be at par of the technology presented with Fidalgo and eventually supersede it. I encourage you to regularly review the Orcas CTPs to understand how these features will be presented in that release.
