This is a problem that has been eating at me for a while, and I just haven't found a good solution (no pun intended) for it.
I'm using Visual Studio 2010 with Subversion and Ankhsvn. It works very well, however, my biggest problem with it is that it only retrieves and manages files that are "included in the project". This is great in many situations, but kind of sucks when you want a folder with objects that you want to include in the solution, but do not want to have in the project itself (in this case a web project).
In this case, I want to include some 3rd party DLL's into source control (so they can be kept up to date when syncronizing with version control). I don't want the developers to have to install the 3rd party dll's seperately. What normally happens is that you reference the DLL's from some other location and they get copied into your bin folder at compile time.
I do not wish to include them in the project because i don't wan them copied to the web server when I publish the site (other than via the bin directory where they should be). I thought of creating a seperate project for these, but that would create a useless dll with no purpose that would then get copied to the bin folder because it's referenced.
I've also tried to check them in from the bin folder, but this has caused a number of problems where files did not syncronize prolerly, with subversion saying things about an already version folder being present etc.. This seems to be a subversion or ankhsvn problem rather than a visual studio one. As such, i try to keep the bin folder untouched by version control.
How have you solved this problem in your projects?
