Basically you answered your own question. VB.NET has all the same features as C#, evolved over the same time, but VB.NET has a bunch of additional "crap" held over from a language and environment that it isn't compatible with anymore. That's how it's more complex.

You didn't even consider in your example that you declare variables with the keyword "Dim". Do you even know why? It's meaning has almost been lost to history and makes little sense for what it's used for now.

In fact even before type inference I always thought that Dim was a better idea. It was kind of absurd to be forced to write your type twice.

  Dim D as New Dictionary(Of String, String)

  Dictionary<string, string> D = new Dictionary<string, string>();

Var means variable.

In VB6/VBA, the Dim New syntax actually had different semantics; it would create the instance on first access instead of when the Dim statement was executed. It also had the fun side-effect that setting the variable to Nothing would destroy the instance but anytime you accessed that variable it would just create a new one. Irrelevant now, I guess, but still a nice bit of trivia.

    var d = new Dictionary<string, string>();

`Dim`, a poorly worded keyword by today's standards, is a perfect example of the kind of leftover crap that C# doesn't have today that VB still does have.
