I just installed all the Feb CTP stuff, (WinFx, Win SDK, and ORcas extenstion for VS 2k5), and I have an error when I want to create an new WinFX Application :
- "the project \documents and settings\myuser\local Settings\temp\ezaeuiaoeuaz.gun\Temp\ApplicationData1.csproj cannot be opened)."
and
- "The project type is not supported by this installation"
Thanks for help.

Cannot Create WinFX Application after installing Orcas

Please make sure when you create a new project that the path for the project is not in your temp folder.
Are you setting the project name to be "ApplicationData1", or is that happening automatically from using the template

I'm running into the same problem with the June CTP. I've installed and removed previous versions on the machine.
Interesting your comment about the temp directory. The dialog that comes up indicates the WPF .csproj file is in some strange temp directory:
The project file “C:\…\Temp\<projname>.csproj" cannot be opened. The project type is not supported by this installation.
If I remove the project guid line from the template, it will at least open...
<ProjectTypeGuids>{60dc8134-eba5-43b8-bcc9-bb4bc16c2548};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}</ProjectTypeGuids>
I just don't get some features. I've tried uninstalling/redownloading/reinstalling the Orcas June CTP, but I still can't get it to work. Somehow these project guids must not be registered properly with VS

I'm using the WinFX Application template.
And if I open an existing winfx project, it opens and compiles it fine !
