Ok, so I have VS 2008 and SVN. When I "rebuild all" a handful of my .dll's disappear from my bin folder.
I have these .dll's in a library folder and that's where I am referencing them from.
When I go to publish the app the publish fails, I think they are related. When I reboot my web.config (change something and save) this error goes away. However, the publish still fails.
When I go to the folder and update svn puts all of them back of course, but then it just happens all over again.
Thank you.
I assume that by "Bin" folder you mean the build location where Visual Studio assembles the executable version of your application.
Generally, I've found that making manual changes to the Bin folder is a good way to encounter "a new world of pain". My problems went away as soon as I started letting Visual Studio do what it wanted with the directory and I left it alone.
If you have DLLs referenced from your project, mark them as "Copy Local" (select them in the Solution Explorer, configure in the Properties panel) and Visual Studio will ensure they're copied across for you.
A side note: As the Bin directory is managed by Visual Studio and is completely reproducible, I suggest that it (and it's sibling Obj) shouldn't be under source control.
