I found the Membership.GetUser() but it doesn't seem like it supports
retriving user information by the UserId Guid. Does anyone have a nice
and clean way of doing this?

```
public MembershipUser User { // get...;set...;}

```

my code is fail here...

```
User = Membership.GetUser(dr.GetValue(dr.GetOrdinal("Id"))); //fail

```

error message: `specified method is not supported`
