MVC 1.0, .Net 4.0, and Expression Blend 4

I am trying to open a MVC 1.0 project compiled with the .net 4.0 framework in Expression 4. The solution opens fine, but there is no intellisense and when I run it, it shows an ht开发者_StackOverflowml browse page with the files listed. Any ideas on how to get Expression 4 to play nice with MVC?

Thanks
