SharePoint not installed

I suddenly run into this error when I try to create a new project based on a SharePoint Template using Visual Studio 2010 Beta 2. It doesn’t matter which template I choose, Visual Studio always prompts this while creating the project:

SharePoint Not Installed

A SharePoint Server is not installed on this computer. A SharedPoint server must be installed to work with SharePoint projects.

For sure, a SharePoint server is installed on this computer! It’s all on the same machine, and SharePoint has been installed first and is running.

Anyone out there had the sample problem? And any idea?

UPDATE

Well, I got an answer, a sad one.
In Visual Studio 2010 Beta 2, SharePoint Projects against SharePoint Server 2010 prior to Beta 2 are blocked.

See here: http://social.msdn.microsoft.com/Forums/en-US/sharepointdevelopmentprerelease/thread/60cc9b09-0bd7-4f0a-aaaf-1224030bd127

So, I have to install VS 2010 Beta 1 again.
