Essential .NET, Volume I 286

hmobius writes "In a world where developers are baying for customers' attentions, very few people can claim to command that of the developer. Their blogs may be the only clue to the higher level of thinking that they operate at, creating the answers to why and when code works in addition to the perennial how. Whether he likes it or not, Don Box is one such system-meister. He may dislike writing books, but when one comes out, people pay attention and read. His first foray into text, Essential COM, was the book to explain how COM worked, and his latest, Essential .NET, takes the .NET Framework's Common Language Runtime (CLR), and does exactly the same." Read on for the rest of hmobius' review.

summary Great in-depth look at the CLR, but not for developers aiming to better their skills.

After chapter one's history of the evolution from COM to the CLR, the book takes a bottom-up approach to the CLR, starting with a deep and detailed six chapter look into the core elements of the platform. Chapter two begins with assemblies, the programmatic units in the CLR, and the implications of their construction. We learn how they are versioned, loaded and built, and why therefore they may be written in as many .NET languages as required. There's real depth to the material here -- you really do touch the bottom of the abyss, so to speak -- but it's countered with occasional levity that keeps this a readable book instead of a dense reference manual. The same is true of all the text. To wit, there's even some irony; "To allow old dogs to avoid learning new tricks, there is finalization," he declares in the next section on the Common Type System.

It's here that we discover how different types and interfaces are distinguished from themselves and from one another, and how their variations and relationships are kept separate by the CLR. It's refreshing to note that the proverbial big picture is never very far away from the commentary. After taking time to explore the avenues for types and interfaces, Box notes that types themselves aren't very interesting until you start working with instances of those types, and we're off again working through another thirty pages on how object instances preserve a sense of identity, how they are cast into other types and how they incorporate themselves into the concepts of reflection and metadata. Only then do we look at the actual lifecycle of an object, its creation, modification and disposal. The attention to detail is great, and there's little ambiguity in the text, but with that comes a slowness to this section that may leave readers frustrated.

One recurring theme of the book is the idea that while there is a very proper way and set of rules for doing things, there will always be circumstances in application development which call for exceptions to be made to those rules and made possible by .NET. This is true at a small scale and, as chapters six and seven prove, at a large one too, covering as they do how the CLR calls and runs methods first on a single machine and then over a wire. How does the runtime treat methods called explicitly, implicitly through a delegate, asynchronously, or as a combination of the three? How do remote calls and types bridge whatever gaps they must cross and activate the remote objects and methods they're targeting? The answers are here.

Essential .NET reflects Box's pride in .NET and also his slight dissatisfaction with it. You can sense that while he knows .NET version 1 is an improvement over COM, it's not as good as it could be and things are still be done in v2 and beyond. Chapter eight's look at AppDomains and in particular its discourse on threading within and through AppDomains is a good example of this. Meanwhile, we finally come full circle in our investigation of the CLR, seeing how the assemblies we built in Chapter 2 are resolved and executed within AppDomains. Exceptions to rules being included, we also see how objects references are marshaled across AppDomains for inter-application communication if this is required.

The last two chapters look at wider topics around the CLR in as much detail as they can for topics which have entire books dedicated to just them. Chapter nine covers code-access security and chapter ten topics which are not of the CLR but which be can be addressed from within a .NET application: explicit memory management, using p/invoke to import COM methods from DLLs and so on. Both are concisely written and to the point, but unsurprisingly leave you feeling like there's more to these topics than is covered here. Chapter nine is a great and clear introduction to code-level security, for example, but you'll get a lot more out of Michael Howard's book, Writing Secure Code if you want to know more.

Essential .NET isn't an easy read but everyone should try to read it at least once. Focusing on the CLR itself and how it deals with the components of an application means that it truly is aimed at the community of .NET developers as a whole (including those building and using alternate implementations of the CLR). The provided code examples are expressed in C#, but this is incidental, really, and won't stop VB.NET, J# or any other developers getting a great deal out of this book.

This is a dense, complex volume that requires a fair amount of effort to understand and use, and to some extent this may put people off. On the other hand, it is so packed with great nuggets of information that they may be inspired to keep reading. Of course, there is the question of whether this book will actually improve your .NET development skills, but in riposte, you can honestly say that no volume details the CLR and its potential so well, and that this alone is worth the book's cover price.

    I'm with the rest of /. when I say that I would rather be on a UNIX based platform, but like many of you due to my job I am forced to deal with a Windows Server environment if I like it or not, and as much as I have tried to hate it, I have actually been quite impressed with what you can do with Visual Studio and .NET
    When you write a .NET web application you use the same code (meaning VB.NET, C# etc, as opposed to ASP, or VB Script) that you would use when writing a desktop app, and the fist time the page is accessed, the web server compiles all the code into dll's on the fly. Converting my existing ASP apps into .NET has tripled the performance using the same hardware. This method is very very fast. Fast to develop and fast to benchmark. It would take me months to write a C/C++ cgi app to do the same thing that I can pump out in an afternoon with VB.NET. And more intuitive I might add.

        The big difference between the ASP.NET paradigm and that of, say, Java Servlet Pages, or XSP, etc. lies in the event-based nature of ASP.NET pages.

        Each ASP.NET page is an instance of the "Page" class, or one of its sub-classes. The "Page Lifecycle" defines the various phases that apply each time a page is accessed. The "Page" is simply the top-level node in the "control tree", and each control in the tree does the following for all its children (recursively):
        1. initialization
        2. handle postback data
        3. state management
        4. handle events
        5. pre-render stuff
        6. render to HTML (or whatever)
        7. clean up

        Most of your code will pertain to numbers 4 and 5 above, if done correctly.

        It's not immediately intuitive, coming from a Web App developer's perspective, but does provide a good general structure and mechanism.

        In addition, each Page is split into its actual class (the so-called "code-behind page"), and its representation as markup (the .aspx page). The .aspx page is parsed on each request, but the code-behing is pre-compiled.

        ASP.NET provides a robust programming model for web applications, but it also provides a lot of built-in mechanisms for doing common stuff. Authentication, Authorization, Caching, DataBinding, XML, conditional rendering, templating, data access through ADO.NET, internationalization, Debugging and Tracing utilities, and more.

        That said, I find the event-based programming model quite difficult to master. If used improperly, you can end up running the same code many times; for instance of you populate a given control (say a dropdown) from a database, and do so in response to many different events. Better to flag things and then fetch just once from the DB prior to rendering.

        Thoughts?

        PS: At the moment, you can't mix multiple languages (C#, VB.NET) within a single Web App.

          The big difference between the ASP.NET paradigm and that of, say, Java Servlet Pages, or XSP, etc. lies in the event-based nature of ASP.NET pages.

          Each ASP.NET page is an instance of the "Page" class, or one of its sub-classes.

          This is not a new invention of .NET, as these concepts go at least as far back as Java Server Pages. Every JSP page implements JspPage (or HttpJspPage), and follows roughly the same lifecycle. The container typically provides that JspPage class, though a developer can roll his/her own, as well. (Before people jump all over me, yes, in the Java world, people rarely put the page as the top controlling object, preferring to use a Servlet as the controller and the JSPs only to render the final view.)

          This is not to take anything away from .aspx -- some of it is quite nifty -- but the basic concept of a "Page" object and "Page Lifecycle" is not new to .NET; Java has had it for a while, and I am sure some geek out there will point out even older examples.

        • The big difference between the ASP.NET paradigm and that of, say, Java Servlet Pages, or XSP, etc. lies in the event-based nature of ASP.NET pages.

          Anyone in the J2EE community looking for similar event-based behavior should be keeping an eye on JavaServer Faces [sun.com]. One big problem is getting it to work on the existing JSP architecture, though, as JSP still has no server-side component model.
        • PS: At the moment, you can't mix multiple languages (C#, VB.NET) within a single Web App

          No, and I'm not sure why you'd want to exactly, as it would be better perhaps just to pick one language and stick with it. However, if you had a need to use both, you could encapsulate say C# code behind a web service (simple to do in .NET) and call from VB. If everything is on the same box, there shouldn't be any additional overhead.

      You should always write web application using a platform that allows you to use the same infra-structure you use for desktop application. Besides the learning curve problem, it also helps when you wnat to mix them both ("weblize" a destop app, for instance).

      That said, ASP and VB.NET are not the answer. Using non-portable languages to write web apps is a very bad idea.

      Where are you from, 1994? If you really need unmantainable spagetthi like ASP, you can use PHP (portable across all known platforms), but you have Java (Tomcat) and Python (Zope) that allow you to use very high-level structures with a higher productivity (in my experience) than any Windows-only solution.

    You know, the "registries" and "assemblies" are getting so complex that I would rather they be stored and managed in a relational database. The rules and tools for relational databases are better understood and apply to many areas, reducing one's learning curve and let's them use existing tools to analyze data and structures. I can look at the schemas and data dictionaries (schemas with extra info, such as field descriptions), and fairly quickly get a feel for how the different entities work and relate to each other.

    A proprietary structure just ends up reinventing a lot of database wheels like concurrency, backups, change logging, etc., and has unfamiliar access protocols, often mirroring the "navigational databases" of the 1960's.

    I know, some of you say that I have an "if all you have is a hammer, then everything is a nail" view about RDBMS (relational databases), but when structures become non-trivial, then nothing beats a RDBMS in most cases.

      The only Java implementations you can get are all based on code licensed from Sun. With the JCP, Sun stifles innovation and progress. And Sun holds numerous patents on Java technologies, making it unlikely that the platform will ever be truly open. With so much control over Java, it is particularly worrisome to see Sun's market evaporate--Sun is a company on the way down, and the question is: what will they do to/with Java before they hit bottom? An SCO-like scenario involving Sun, IBM, and open source implementations seems entirely plausible.

      Both Java and .NET are attempts by two big competitors to establish new proprietary platforms and to do an end-run around open source systems like Linux. If a large fraction of the software on Linux were done in Java, for example, Sun could basically give their own platform an advantage by tinkering with the Java-on-Linux implementation.

      The solution? Don't use either. Mono may be a way out because, in addition to a .NET compatible set of libraries (which you shouldn't use and which may be encumbered by patents), it is getting its own, native set of APIs.

      But if you want to avoid the issue altogether, just don't use either Java or C#--there are plenty of good alternatives around. In fact, most software these days should probably be written in languages like Python, with a few core C/C++ libraries for numerical and other high-performance subroutines.

Should every derivative product be denounced as coming to the table too late? I think not. Once more, .NET ( the bits for developers anyway) brings some better things to the table as well (as evidenced by Sun getting into the leapfrog game with Java v.Next features - Metadata (Attributes), etc).
    • Imitation is flattery, but imitation without acknowledgement is plagiarism. Microsoft appear (at the very least) to strongly discourage their employees from discussing how much .NET owes to the Java platform and how much C# owes to the Java language, even though anyone who knows Java can see that 80-90% of C# came directly from Java.

      It's good that C# is competition, in some domains, for Java, and seems to have pushed Java's evolution forwards (new features for Java 1.5 are similar to things in C#).

    This is one of the best .NET books, the first of a series of pretty good books, by those involved deeply with the framework.

    This book covers the technicalities in the .NET framework, and is of special interest if you are interested in the advanced features of the Common Language Runtime like method interception, transparent proxies, application domains and metadata.

    Compiler writers, framework developers and those who need to get the most out of the framework will be interested in this title.

    I can not recommend this book enough. Don has done a fantastic job. It helped the Mono developers understand the low-level technical features of the framework.

    I'm seeing a lot of blind flaming about .net, so here's my overall response. .net (all lowercase, not ".NET") is Microsoft rearchitecting Windows across the board. You don't use the Win32 API any more; you use the .NET libraries. You don't write applications in raw C++ any more, you use C# or another higher-level language that targets the CLR (Microsoft gave advance information to a number of indepdendent language developers, encouraging them to port their products to .net). Security issues caused by low-level buffer overruns have vanished. You get a nice Visual Basic-like environment for creating GUIs. This is all a great idea.

    The downside is that while .NET and C# are much better than the Win32 API and C++, there's a general staidness to it all. It feels like we've moved from 1985 to where we should have been in 1994. C# feels wonderful if you're a C++ programmer who never used Turbo Pascal or Visual Basic (or if you're a Turbo Pascal or Visual Basic programmer annoyed with C++), but it feels overly complex if you've used a dynamic language like Python, Smalltalk, or Lisp. The OOPness of .NET is very heavy and static. And it's all still based on a compile-run cycle, which is hard to go back to once you've gotten away from it.

    Personally, even though I think Microsoft is correcting a lot of past mistakes with .NET, and even though Microsoft is showing a lot of initiative and is willing to throw out a lot cruft we've all gotten used to, I don't think it's enough. The result is still complex enough and elaborate enough that it's tough to bank on it as the future.
