• Answer:

  First of all, try to find out what other processes are still holding a lock on the DLL file. You can do this with SysInternals Process Explorer. http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx Make sure you launch Process Explorer with Administrator rights. Perform a handle search for the name of the DLL. This will scan the handles and process space of other applications, and list any applications that has a handle to that DLL. Without identifying what other processes are holding the DLL back, there is nothing else you can do. One possible way of avoiding a lock on a DLL is to make a shadow copy: copy the original DLL to a temporary folder (with a folder name generated from some nearly-unique random function), and then load the DLL from there. If there is ever a need to load a DLL with the same name but different content (say it has been recompiled), generate a new random folder name each time. You can see how it works by taking a look at the NUnit project. By default, it makes shadow copy of all of the DLLs (both the unit testing project and all of its dependencies).
