Question

I don’t want a war between VB.NET and C# developers, neither is my goal to open a C# VS VB.NET confrontation.

I would like you all to list a feature that is heavily used in C#, but is not available in VB.NET 2.0, and how would you work around to achieve a similar behaviour or purpose?

For example:

C#

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 is impossible to do before VB.NET 4.0 (supposed to be doable in VB.NET 4.0)

VB.NET

Must write a helping method (Sub), and provide the AddressOf this method in order to workaround.

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, it is not VB.NET 2.0, but this is an example. VB.NET 3.0 and 3.5 can used too. Please just mention what version of VB.NET this refers to.

You could check out the wiki for a comparison. See sections “Features of Visual Basic .NET not found in C#” and “Features of C# not found in Visual Basic .NET”.
