Can't build vnext project

I'm trying to develop an application using vNext (August CTP plus Linq May CTP), but I get this error:

Error 2 The type 'System.Query.IQueryable`1<T0>' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Query, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. c:\Program Files\Microsoft SDKs\ADO.NET vNext CTP\Reference\System.Data.Entity.dll

plus another similar error.

but the reference is correctly added.

I'm using Windows Vista 5536, I installed Linq May CTP then Ado.net August CTP.

Edit: this is the project file:
