The topic of "C# 4.0" is an area we've been diving into a bit lately. So we took this opportunity to sit down with Niner-regular Anders Hejlsberg and C# Community PM Charlie Calvert to dive into some of the most common questions we are hearing about C# 4.0 and the reasoning behind some of the answers.

If you are not familiar with C# 4.0 or want to dig into some other C# 4.0 resources, make sure to check out the following videos:
- [PDC] The future of C#, Anders Hejlsberg
- Inside C# 4.0
- C# 4.0: Meet the design team

Also make sure to check out Charlie's blog and some of the resources he and the team have made available on MSDN:
- New C# 4.0 Features Paper
- Covariance and Contravariance in C# 4.0
- Community Convergence 47

Another great vid from Anders. I don't have an especially smart comment other than to say I appreciate these and look forward to the next time we see him on Ch9.

Must come as a matter of taste.  I strongly prefer the XElement method to the VB inline method.

No difficulties in having to line up ending tags.  Its XML exploiting the C# parser.

Will Visual C++ status quote  be enough to overcome the appeal of the D programming language in 2010?or is C# going to be unleashed? 

Why doesn't Visual Studio provide for two forms of compilation.  For example the exiting just in time and full compilation of the MSIL to  machine code.  I really see that C++ at this stage only serves for the purpose of maintaining legacy code.  The incarnation of C++ was a hack and will continue to grow as a hack.  .Net languages (in particular C#) for one should take full charge of future development in both desktop, web and yes system development. D programming language is already making an impression on  a small but growing  C++ community.  D programming languages has syntactic appeal of C# and the horse power of C/C++.  So what is the constraint,  religion or technical feasibility. DotNet languages will be competing against the up an coming D programming languages sooner or later for development of system software and embedded systems. Again I say C++ is dead weight and should only be relevant for legacy code (in other words C++ will soon be Cobol).  C# (all .net lingos) can easily take the manto if Visual Studio provided for this option and full support for "producing"  applications that are true  platform independent.

Well, I can see a some nice scenarios to use this.

But I had hoped for something much more powerful Smiley

private string Foo(int x)
{
    return x + 10;
}

public DoSomeThing(Method name)
{
    var fooValue = name(10);
}

public Caller()
{
    DoSomeThing("Foo");
}

That's what I call dynamic Big Smile OR even more useful, dynamics for class names also.
