Need help resolving an error when passing a query to a View...

I need help resolving an error... and may need an advice for a better implementation. I'm still trying to grasp the LINQ concept so I am stumbling along the way. Basically I just tried querying the aspnet_Users and aspnet_Membership tables and displaying the values to a view (not strongly typed)

This is a working test code

From HomeController ------------

var test = new TestEntities();
ViewBag.UserIds = (
from m in test.AspnetUsers
orderby m.UserId ascending
select m
);

return View();

From Home View -----------------

<ul>
@{
foreach (var x in ViewBag.UserIds)
{
<li>ID: @x.UserId</li>
}
}
</ul>


But this one gives me an error: {"'System.Guid' does not contain a definition for 'UserId'"}. I'm still using the above View for this.

var test = new TestEntities();
ViewBag.UserIds = (
from m in test.AspnetUsers
orderby m.UserId ascending
select m.UserId
);


And this code too (since it's related above).

var test = new TestEntities();
ViewBag.UserIds = (
from m in test.AspnetUsers
join n in test.AspnetMemberships on
m.UserId equals n.UserId
orderby m.UserId ascending
select new
{
m.UserId,
n.Email,
n.CreateDate
}
);


How can I resolve this error? Is there a better way of passing the result of a database query to a view which is not strongly-typed?
