What features are heavily used in C # 2.0 but not available in VBNET 2.0, and how do I get around?

I don't want a war between VB.NET and C # developers, and my goal is to open the C # VS VB.NET confrontation.

I would like you all to point out a feature that is heavily used in C # but not available in VB.NET 2.0, and how would you work to achieve similar behavior or goal?

For instance:

FROM#

Accepts void (return) lambda expressions. Here's an example with FNH mapping:

Component(x => x.Address, m => { 
    m.Map(x => x.Number); 
    m.Map(x => x.Street); 
    m.Map(x => x.PostCode); 
});

This cannot be done before VB.NET 4.0 (assuming it is executable in VB.NET 4.0)

VB.NET

Should write a help method (Sub) and provide AddressOf this method to work around.

Private Sub Helper(ByVal m As MType) 
    m.Map(Function(x) x.Number) 
    m.Map(Function(x) x.Street) 
    m.Map(Function(x) x.PostCode) 
End Sub 

...   
Component(Function(x) x.Address, AddressOf Helper)

Now I know this is not VB.NET 2.0, but this is an example. VB.NET 3.0 and 3.5 can be used too. Please just indicate which VB.NET version this applies to.

You can check the wiki for comparison. See "Visual Basic.NET Features Not Found in C #" and "C # Features Not Found in Visual Basic.NET".

Iterator blocks (return / yield) are probably the largest.

For me, something I missed is the implicit interface definitions:

ISomething
{
   void Execute();
}

class ASomething : ISomething
{
   public void Execute()
  {
    //Do something
  }
}

Perfectly. In VB.net, you have to explicitly mark a method as an implementation of an interface, which I find quite annoying. I know there are people who prefer this technique, but not for me ...

An unsafe block of code using a keyword is unsafe

not allowed in VB.NET. There is no workaround. But to be honest, I have never used this feature. If I come across a situation that usually requires this feature, I usually kick and navigate right into C ++ / CLI.
