Am I missing something or does that "Open in blend" option in Visual Studio 2008 not exist anymore?
I am using VS 2008 SP1 + Expression Studio 3.0.
I can do it the other way around, from blend to visual studio, but not visual studio to blend.
Cheers
For me, the "Open in Expression Blend" is only available in Silverlight projects, for WPF projects the option does not exist.
I had the same problem, I had the trial version of blend, uninstalled and then installed Expression Studio (from my MSDN subscription). The option in Silverlight projects was gone.
I found here that all I needed to do was to add the following registry entry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Expression\Blend\VS\BlendLaunchPath
And this should point to the full path where expession blend is (in my case: C:\Program Files\Microsoft Expression\Blend 3\Blend.exe)
After this all I needed to do was to restart Visual Studio and there it was again!
Hope this helps.
