Visual C# Very Slick

I must confess, I’ve always been a fan of Microsoft’s IDEs for developers. One thing you have to give the Redmondians credit for is that they realized at a very early stage that healthy developer support was the key to maintaining interest and support of their products in the marketplace. To that end, they released more APIs, SDKs, and IDEs than you could shake a large stick at, and some of them were even quite good. The Visual Studio family of tools, for instance, was a mixed bag, but it had a couple of gems. Alongside the tragic Visual Interdev, the utterly terrible Visual SourceSafe, and the vomit-inducing Visual Basic, there were some slick and useful applications. One of these was ( and is ) Visual C++, which easily wiped the floor with any other C++ IDE, even in Borland’s heyday. This product has matured and improved with age – I recently gave a quick test drive to the Visual C++ 2005 beta whilst fixing a bug in some legacy code, and I was impressed.

Another very nice addition to the Visual Studio family was unfortunately short-lived. Way back when, MS introduced a product called Visual J++. This was their first (and last) step into the Java IDE market. The language was Java, but being Microsoft, it wasn’t 100% “pure” Java – it had some custom extensions that made it very useful in a Windows-only environment. Chief among these was J/Direct, which basically was a mechanism that inserted proprietary bytecode into generated .class files, relying on the extensible bytecode mechanism written into the JVM specification by Sun. This turned out to be really powerful, and a godsend for us (at the time) Windows programmers. It allowed you to declare and invoke native function calls in a similar manner to how VB did, and all the parameter and datatype marshalling was done under the hood. The entire Windows API was at your beck and call, and all for very little effort. A set of wrapper classes for common chunks of the Win32 API was supplied, and was called WFC (Windows Foundation Classes). I remember giving a presentation at a Java conference in San Jose back in 1998 on this stuff, and the Java guys who managed to get over their disgust at me presenting on a MS-specific topic were amazed at what it could do. There were two other great attributes to this package as well – it had a very nice event model (called delegation, which you can find in Visual C#), and a drag-and-drop visual form editor, good examples of which were relatively rare in the Java world at the time. So you got the elegance of the Java syntax, with the ease of GUI construction that at the time only existed in VB.

Unfortunately, it couldn’t last. MS and Sun fell out, and took their mutual dislike to the courts. Visual J++ gradually become sidelined, and then an MS technology evangelist told me at a conference that J++ was quietly being dropped, and a replacement was being mooted (at the time, it was codenamed “Cool”).

Which brings us back to 2005, and Visual C#. What you get when you work with Visual C# is the direct descendent of Visual J++. The same guy (Anders Hejlsberg) has lead the development stream for both J++ and C#, and he has fused a lot of the original ideas of J++ with many (many) more directly from Java. And it’s really, really good. I’m actually going to try and earmark a piece of work that I know will be Win desktop-specific and I’m going to do it using Visual C# 2005. It took me no time at all to knock up a desktop client for CruiseControl, and I was rather pleased with the result.

Of course, there are limitations – portability being the obvious one. But I do think it’s wise to have as many tools at your disposal as you have individual problem areas to attack (also a famous theory in economics). And I think Visual C# will be able to solve quite a few problems for me in the future.
