I do have a question though. Why is C# a "productivity language"? I've searched a bit and read couple threads on stack overflow but haven't found huge advantages in using C# over let's say C++ & QT. I've been programming with C++ for a loooong time now. Why should I pick up C# to further my productivity?
1. The language itself has many features that makes it easier to be productive. You can do more with less lines of code, and the code that you do have to write tends to be less repetitive and more direct. Simplicity and elegance have been major design goals throughout the lifetime of the language. As a result, it's just easier and more enjoyable to use C# than C++. I always find it a little tedious having to go back to C++.
2. The ability to access the .NET Framework Library and all of the related frameworks means a whole lot of code is written for you when using C#. If you just look at some of the namespaces of the .NET Framework Library there is MS Build integration, all the container classes, language generation, SQL Server bindings, OO wrappers around Win32 API Library Functions, CodeDOM, Diagnostics, Drawing, Enterprise Services, IO, Isolated Storage, Ports, Media, Messaging, Network programming, Reflection, RPC, Security, Authentication, Cryptography, Threading, Transactions, XML parsers & Serializers, XPath queries, and tons of Web stuff: Complete HTTP engines, Email classes, various protocols, etc...
In addition to all the basic classes in the .NET Framework Library you also have WinForms for creating GUI Windows applications, WPF, WF, WCF, and ASP.NET.
So I guess the better question is, when you want to write a complex Windows Application with multiple windows, tab controls, tree controls, animations, etc... How do you do it in C++? Likewise, if I asked you to create a database application that made connections to multiple databases, performed transacted queries against the databases and displayed results in a GUI application, how would you go about doing it? How about, write a GUI application that lets you enter in the email address of multiple people, subject, and a message body and then send the message out to all the people in the email list in formatted HTML over TLS secured SMTP?
Most of these things would make the average C++ programmer shiver. At the very least they'd be searching the interwebs for available libraries, and at worst they'd be looking for RFCs on protocols to begin implementing them themselves. In C#, the above programs range from a couple dozen lines of code to a couple hundred (maybe some in the low thousands), because most of the boilerplate stuff is done for you. It's literally half a dozen lines of code or less to open a database connection to SQL database and make a query. The support provided to programmers to develop "every-day" applications is just amazing to me.
