How to copy a DLL to a project directory prior to build?

Question

I'm running an old ASP.NET web site.  The DLL references are copied to the BIN folder.  Contrast this with most modern programming frameworks that will add a relative reference (this method works with CI builds).

To work around this problem, I need to copy the 3rd party DLL into WebSite\Bin folder prior to running MSBuilds tasks.

My thought is to run a Script task just after Source Code Checkout.  The problem I have is I don't know how to locate the 3rd party DLL on the CI build server.  I know the present working directory is something like:

C:\bamboo\xml-data\build-dir\JOBNAME

I need to get access to the relative source control directory:

$\fullPath\3rdPartyDLLFolder\MyThirdParty.dll

So I can do something like this in powershell:

Copy-Item -Path $\fullPath\3rdPartyDLLFolder\MyThirdParty.dll -Destination \ProjectDirectoryOnBuildServer\WebSite\Bin

I'm other to other solutions if there's a better way.

I added powershell's ls command to my Script task.  Then the bamboo log files told me which directories existed because it just output verbatim. My source control path was right there in the present working directory.
