title: Copy referenced assemblies to subdirectory of output directory
body: <p>By setting "Copy Local" to true in the VS2017 Properties window for a .net reference, you can tell the build process to copy a referenced assembly to your project's output directory. But what if you want the assembly to be copied to a specific <em>subdirectory</em> of the output directory (which will be added to the list of search paths via an app.config setting)? Is there any way to do this, short of using a batch file in a post-build step?</p>
