Constructing An Object And Calling A Method Without Assignment

I'm not entirely sure what to call what C# does, so I haven't had any luck searching for the VB.Net equivalent syntax (if it exists, which I suspect it probably doesn't).

In c#, you can do this:
public void DoSomething() {
new MyHelper().DoIt(); // works just fine
}

But as far as I can tell, in VB.Net, you must assign the helper object to a local variable or you just get a syntax error:

Public Sub DoSomething()
New MyHelper().DoIt() ' won't compile
End Sub

Just one of those curiosity things I run into from day to day working on mixed language projects - often there is a VB.Net equivalent which uses less than obvious syntax. Anyone?
