Brief description: We have a few C++ dlls which are targeting 32 bit and 64 bit platforms separately. I want to build my project with the corresponding target platform with the appropriate DLLs being fetched from different source folders. I will make a setup package based on this. I would like your views and approaches to this problem. An easy to implement solution would be great but then again, please pour in your suggestions.

If I understood right, you want add references with conditions?
It may be done by hand editing the project file...
I done it for files (not references), but it may work for you too...

I am wondering about how i can dynamically refer to the 32bit and 64bit dlls since i need the reference. I know i can use reflection but then i will have to write a wrapper for it. This could get tedious. Your solution would be great if i had to include something based on conditions. I could also use the build tab pre build events for the inclusion i believe. Thanks. I am still waiting for the answers to this problem through other ways :)!

An other idea - much simpler - is to create two solutions for 64 and 32, that share the source files, but have different set of references...

Hi Kornfeld,
Yes, we currently are doing the same thing. However if we do manage to roll in a change set, we need to verify and test the change on two different solutions and then check them both on different environments! That is why i am trying to bring them both into a single solution file which would conditionally use the libraries. Your solution works for swapping out the reference. Thanks for that! I am stuck with another issue now though. This is something i'll ponder about for a while i guess.
