Another sad example of how Microsoft manages to overcomplicate things. This is DLL hell, reloaded.

Josh - when we ship QFEs and SPs, we update all redist mechanisms, including app-local DLLs, MSMs and VCRedist*.exe as part of the patch to Visual Studio. I believe we will do the same for the MFC update (although, since it is in the future, I can't say with exact certainty that it will be that way, but that's the current plan as far as I know).

Thanks, littleguru. I assumed we were being forced to use a technology.

sry, its been getting on my nerves since channel9 switched players. I appreciate your efforts.

You can op out... Go to your profile -> settings and disable silverlight for the player.

so in theory MacOS can still suffer from dll hell unless the library directory stores multiple versions of the Library.

Linux systems (I believe it's also in most *nix systems) store the dynamic link libraries in /lib and /usr/lib. with .so(dynamic-linked) or .a(static-linked) in extension.

And they put the version number at the end of the file. Then provide symbolic link to the filename without version in extension as the current version.

======

So you'll see:

libsomething.so -> libsomething.so.4.3.3
libsomething.so.3 -> libsomething.so.3.1.0
libsomething.so.4 -> libsomething.so.4.3.3
libsomething.so.3.1.0
libsomething.so.4.3.1
libsomething.so.4.3.3

In some system that doesn't use package management systems.

======

Note that on most systems, some of these libraries are left behind intensionally for backward compatibility reasons. (e.g.: the *-compat packages)

If you install an application that requires previous version of glibc runtime, just install the current version of glibc-compat and you'll get all the previous versions of glibc-runtime. That's how they solve the DLL hell problem.

@Dark_Halmut

Are you running the lastest Version: 1.0.21115.0?

When the Office Ribbon updates comes, being off band, will there be another VC redist? And why is producing ClickOnce deployments so complicated for native C++ apps? It's not like disk space is an issue... Is disk space an issue?

No, I'm not a "busy guy working with many companies". I'm just a regular tech guy who has deployed hundreds of commercial applications during my life. Do you think it's too difficult to recognize a messed up installation?

Well, it does not look substantially different from Windows...

Just out of curiosity, what approach deos Mac OS X uses (I know they don't have dlls, but they still heave lilbraries, etc.)?

Do they link everything in the binaries? How are updates taken care of in that case?

I do that Charles whenever is possible, but I was not talking about me.
Most of the software industry "big-names" (not to mention 99% of shareware vendors), ignore these guidelines when designing their products deployment.

Sorry but you've managed to make the process of distributing .dlls harder and less reliable than it ever has been.

(SXS will likely join the registry and UAC in the legendary "it sounded good on paper" pile.)
