Visual Studio 2005 beta 2 breaks ASP.NET 2.0 application cache

Cut a long story short (again) - If you have an app running on your workstation that uses the web cache (e.g. HttpContext.Current.Cache) you may notice the cache contents being dropped at seemingly random intervals while developing the app in Visual Studio 2005 beta 2. The bizarre behaviour starts when I open an ASPX page for editing, and then only stops when I close Visual Studio.
