Lambda the Ultimate

It's early days yet, so I am sure the author could use some encouragement and support...

Obviously this is mostly about the IDE side of things (seeing as VS is an IDE).

Some of the features that VS provides are intended to overcome the huge size of the standard libraries, and you might argue this isn't really a language issue. At some level this is indeed a valid argument. However, I think we should pause every once in awhile and wonder whether better programming language abstractions might make modern programming - with GUIs, XML etc. - easier, and eliminate some of the need for huge libraries. In fact, one can argue that LINQ (Cw) is a step in this direction, as regards data access.

It is also worth noting that when IDEs influence the way programming is done, they influence the way languages are used, and thus influence the design space. Programmers demand new language features partly as a response to their experience with the language as it is used in practice.

Finally, the impact on teaching and learning programming shouldn't be overlooked. Students naturally want to produce cool GUI applications and use VS. If this makes it harder to introduce them to different programming techniques and languages (and I think it does), this can be highly problematic.

Here are some choice quotes from Petzold (who also said that the whole history of new programming languages... for Windows has involved the struggle to reduce the windows hello-world program down to something small, sleek, and elegant):

To get IntelliSense to work right, not only must you code in a bottom-up structure, but within each method or property, you must also write you code linearly from beginning to end — just as if you were using that old DOS line editor, EDLIN. You must define all variables before you use them. No more skipping around in your code.

If we select a new project type of Windows Application, for example, and give it a name and location on a local drive, Visual Studio generates sufficient code so that this project is immediately compilable and runable... Somehow, we have been persuaded that this is the proper way to program. I don’t know why. Personally, I find starting a program with an empty source code file to be very enjoyable.

This is the file in which Visual Studio inserts generated code when you design your form. Visual Studio really doesn’t want you messing around with this file, and for good reason. Visual Studio is expecting this generated code to be in a certain format, and if you mess with it, it may not be able to read it back in the next time you open the project.

This bothered me because Visual Basic was treating a program not as a complete coherent document, but as little snippets of code attached to visual objects. That’s not what a program is. That’s not what the compiler sees. How did one then get a sense of the complete program? It baffled me.

If Visual Studio really wanted you to write good code, every time you dragged a control onto your form, an annoying dialog would pop up saying “Type in a meaningful name for this control.” But Visual Studio is not interested in having you write good code. It wants you to write code fast.
