So, what features that were showcased in longhorn have finally made it into Win7/Vista?

To start with:

* Libraries (sort of, I know it's not a full blown WinFS, but still)
* Sidebar/Gadgets
* Navigation tools in Explorer
* Aero
.....

The sidebar in Vista/7 has far less functionality than what was shown in Longhorn demos and whatnot, plus it's not intergrated into the shell.

*Higher resolution icons...
*Folder icons with integrated thumbnails...

It'd be easier to list the things that didn't make it...

Theres also a powertoy for Windows Xp that does the same thing, it's more refined but it won't work on Vista.

Remember when the sidebar was integrated in Explorer? All the memory leaks where Explorer would end up literally using gigabytes of memory.

that was because Longhorns Explorer with integrated Sidebar was made with .NET ( compiles assemblies together when needed ) while XP and Vista/7's is a static "classic" app, most likely done in C,C++ or so - however in a language that will not assemble itself on launchtime but being ready compiled before.

Explorer's Sidebar was pure C#, mixed with "Avalon" and "Indigo" ( pre-net 3.0 "WPF" and "WCF" ) - all these sidebar-tiles would in effect compile in realtime, as they were made of MSIL assemblies - that's the reason your memory gets eaten, because the compiler is running in the background, and it has to render the explorer-bars,the sidebar,the tiles, the frontends to Winfs and what else. The whole scenario was at a minimum as complex as running the application "paint.net", which is also made of NET assemblies. To compare that : every picture-operation, crop,blending,rendering and so is done not via the app, but with the "pieces" of code that are in the Global Assembly cache.

While this functions relative good with a application that is designed to have only one goal ( produce images ) , imagine that complexity to a complete operating system and its filemanagers, system-daemons and so on ..

I can not often enough say that all these .NET integration was the No.1 core for Longhorns failure ( with WinFS performance killer being the second ). NET apps need not only horsepower from the CPU and the Memory but rely on the MSBUILD engine all the time, cause this alone is what makes them running.

small applications with one specific goal in mind ( say nlite/vlite) are wonderful examples how powerful .NET is.. but really that's about all. Building monsters like Filemangers,taskbars,Explorer-Bells and Whistles,Extensions and what else with it with NET is insane. Welcome to the Longhorn Desaster where MS did all that.

See for yourself what tiny fraction of Net has made it into the final products.. Even the new xps viewer in 7 is no longer dependent on NEt3.0's WPF.

try launching "vlite -extreme", this gives the option to rip out everything in vista that is net-related and the OS will nevertheless be usable. It is only a add-on but not hardcoded to the OS. Longhorn was originally developed with that in mind, making a pure .net OS.

A bad idea .- MS learned it the hard way.
