Lost some intellisense in VS2010

Getting to grips with Visual Studio 2010,

This compiles:

var x = System.Web.Security.Membership.GetUser();

And runs, however VS2010 gives no intellisense for x and reports it just as a 'local variable'.

Has anyone go开发者_如何学运维t any ideas?

this perhaps?

if you have upgraded your preferences are copied, however if you have something like resharper installed your intellisense preferences are actually turned off as resharper reimplements this.

VS2010 messed up, even though it was telling me the project was running at .net 4.0, changing it to 3.5 then back to 4.0 again fixed it.
