i am using some libraries and i added a reference to that library dll and i set the \"Copy Local\" to true.
but i want to change the location of the dll to be a subfolder in
You'll need a .config file for your .exe so that the probing path is changed. A subdirectory is no problem, just use the
element, its privatePath attribute is a relative folder name.
Beware however that you'll get little help from the IDE to put the DLL in that spot. You'll need a post build event that creates the folder if necessary and xcopy's the DLL there. Something like this:
if not exist "$(TargetDir)mumble" mkdir "$(TargetDir)mumble"
xcopy /d /y "$(TargetDir)something.dll" "$(TargetDir)mumble"
