If you like Object Pascal (Delphi), but for some reason you like the VS.NET IDE more than Borland’s IDE, then you might have a look at Chrome. It is a innovated version of Object Pascal, suited for .NET. Currently, the commandlinecompiler is released as a preview (beta) version, for the .NET framework and for Mono.
I liked Borland’s IDE more, because it has early databinding, so you can see data from a database at design time. It makes the designing easier, since you can see earlier if data needs more of less space in a datacomponent. With the new Delphi, it turns out that this is only the case with BPD.NET and not if you only use non-Borland components. Taken that into account, I think VS.NET IDE is better. It’s faster to load, and more stable on my system. Furthermore, as I blogged earlier, VS.NET is much cheaper.
