# 2010 All-in-One For Dummies represents a different way of looking at programming languages Rather than present the standard For Dummies format, which includes only 350 pages on quite a large subject, the book was expanded to include a broader scope and just a few pages were added So, although you find all the original C# For Dummies goodness in this book, you also find discussions about Visual Studio, Windows Presentation Foundation (WPF), service-oriented development, Web development, and a host of other topics This book is a one-stop shop for a C# developer The C# programming language is a powerful and, at some nine years old, relatively mature descendant of the earlier C, C++, and Java languages Programming with C# is lots of fun, as you re about to find out in this book Microsoft created C# as a major part of its NET initiative The company turned over the specifications for the C# language to the ECMA (pronounced ek-ma ) international standards committee in the summer of 2000 so that any company can, in theory, come up with its own version of C# written to run on any operating system, on any machine larger than a calculator When the first edition of this book was published, the Microsoft C# compiler was the only game in town, and its Visual Studio NET suite of tools was the only way to program C# (other than at the Windows command line) Since then, however, Visual Studio has undergone three major revisions the latest is Visual Studio 2010 And, at least two other players have entered the C# game You can now write and compile C# programs on Windows and a variety of Unix-based machines using implementations of NET and C#, such as Mono (www mono-projectcom), an open source software project sponsored by Novell Corporation Version 12 was released in November 2006 Though Mono lags Microsoft NET by half a version or so, it appears to be moving fast, having implemented basically all of NET 11 and much of NET 20, along with those versions of C# Both Mono and a less well developed competitor, Portable NET (www dotgnuorg/pnethtm), claim to run C# programs on Windows and a variety of Unix flavors, including Linux and the Apple Macintosh operating system At the time of this writing, Portable NET reaches the greater number of flavors, whereas Mono boasts a more complete NET implementation So choosing between them can be complicated, depending on your project, your platform, and your goals (Books about programming for these platforms are becoming available already Check online booksellers)
What s New in C# 40
Open source software is written by collaborating groups of volunteer programmers and is usually free to the world A description of how to make C# and other NET languages portable to other operating systems is far beyond the scope of this book But you can expect that within a few years, the C# Windows programs you discover how to write in this book will run on all sorts of hardware under all sorts of operating systems matching the claim of Sun Microsystems Java language to run on any machine That s undoubtedly a good thing, even for Microsoft The road to that point is still under construction, so it s no doubt riddled with potholes and obstacles to true universal portability for C# But it s no longer just Microsoft s road For the moment, however, Microsoft Visual Studio has the most mature versions of C# and NET and the most feature-filled toolset for programming with them Note: Though three authors contributed to this book, saying I rather than we throughout the main text seemed more economical, so that s what we (or I) do throughout
What s New in C# 40
Although much of C# 40 is still virtually the same as the previous version, this new version adds some exciting new features, most of which revolve around COM Interop, to assist with Office development The big new additions that this book covers include these topics: Dynamic types: Functional programming is all the rage these days, with the cool kids programming in Ruby and Haskell Functional programming certainly has some benefits that have a place in the more tightly woven world of C#, and dynamic typing is one of them As supported in C++ and Visual Basic, dynamic types allow runtime declaration when you don t know the type of a variable and then have the compiler figure it out Properly used, dynamic typing is quite powerful; poorly used, it s quite dangerous Named and optional parameters: In C# 30, you had to provide a value for every parameter in a method call In C# 40 again, to optimize interactions with COM you can mark parameters as optional and accept outside objects that have optional parameters Variance in generics: Although objects in previous versions of C# are variant, generic collections of objects are invariant This statement means that although the compiler accepts an apple when you re asked for a fruit, it doesn t accept a basket of apples when you re asked for a basket of fruit This issue is fixed in C# 40
