VS2008 & VS2005

I have installed both side-by-side. I achieved 20% performance gain on my C++ program when recompiled with VC++ 2008. However, my mixed assembly (C++/CLI & C++) app runs 10x slower! Puzzles me.

You can give the full path of devenv.exe in "HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\Windows\CurrentVersion\App Paths\devenv.exe” Ref: Tips : devenv.exe Problem

I have VS2003, VS2005 and VS2008, all pro editions and all living happily together.

Brilliant, thanks

You're probably messing with the compiler's ability to optimize.

Thanks for the tip. This is definitely useful since when we are to frequently use 2005, then we can toggle this path as appropriately.

Why? So far I've encountered no problems with VS2008 Multi targetting. All of our 2005 projects compile in the same way in 2008.

Because if you build commercial software, any change to your development environment disrupts the stability of the product you are building. Windows applications that supposedly live side-by-side all too often trample each other's registry settings, file associations, temporary file usage, and so on. All too often the reply from the software author in this case is either a blank stare, or at best "Oops. Sorry about that." To their credit, I've not had problems with running various versions of Visual Studio next to each other. That said, it's still reasonable to ask the question each time they release a new version.

Thanks, Declan. We have been 'stuck' with using VS2003/SP1 for some time now. We're about to start a major new development effort, and I have been pushing the idea of switching directly to VS2008. I would like to install VS2005 and VS2008 on my development box and give them a try before we decide which version to buy another dozen seats for the other guys in my group.

No problems on my end. Make sure you don't open and convert any solutions files that you still plan on using in 2005. :suss:

Has anyone tried installing them side by side? Are there any incompatibility issues? I specifically mean VS2005 professional and the VS2008 express editions.

Yes, I have and no problem at all. Only issue I have had is that the components will not drag from the toolbox onto grids ( I suspect this has to do with the machine and not the version of VS being together). The drag-n-drop issue seems to be something I cannot reproduce on my other machines, though.

why every time Ms releases a new version of Visual Studio or Office, that question of cohabitation comes back ?

Maybe people are hesitant in finding out if there are any issues. This is what I use virtual machines for :->

Sure does, and that reminds me to go and buy a memory upgrade for my laptop next week ( a birthday present to me from me :-D ). I only have 512mb in it right now, and have room to go with a 1gb module to increase it to 1.5gb...

You're being punished for straying from the one true path that is managed code.

The problem is, the guys writing the compilers and development environments aren't building mission-critical applications. It's like they're making a wrench used to build the Space Shuttle, and every so often one comes off the assembly line made out of styrofoam.

You should definitely go for VS2008, one big plus is that you can compile against .Net 2.0 and above so if you don't want to run .Net 3.5 in a production environment yet, you can just build .Net 2.0 apps for the moment.

I too have VS2003, VS2005 and VS2008, all pro editions and all living happily together. No problem occured so far for me.
