Visual Studio copy dll from project folder to bin folder on build solution
If we want to copy from project folder DLL (3rd party or other type) to Bin folder during build the solution we can easily map that option.
right click on you solution -> Properties -> Buld Events and follow the format for your folder
C:\Windows\System32\xcopy /d /y "$(ProjectDir)PackagedDLL\FAX\*.*" "$(TargetDir)"
In my case FAX is my folder name.
