If you have dependencies that should be compiled and distributed with the plugin package, then you will need to mention these from the plugin manifest.  The following example demonstrates how you can add a reference (e.g. Rws.MultiSelectComboBox.dll) that should be included with the plugin package + unpacked in the unpacked plugin folder when Studio launches.

<?xml version="1.0" encoding="utf-8"?>
<PluginPackage xmlns="http://www.sdl.com/Plugins/PluginPackage/1.0">
	<PlugInName>Multilingual Excel FileType</PlugInName>
	<Version>1.0.0.34</Version>
	<Description>Multilingual Excel File Type</Description>
	<Author>Trados AppStore Team</Author>
	<RequiredProduct name="TradosStudio" minversion="17.0" maxversion="17.9"/>
  <Include>
	  <File>Rws.MultiSelectComboBox.dll</File>
  </Include>
</PluginPackage>
