I am trying to do my first .Net app. I am using Delphi Developing Studio 2006. I am trying to use a third party product called dtSearch. They have an .Net api. I am trying to add a reference to the api. I went to the menu Project|Add Reference. I looked at that list under the .Net Assemblies Tab but the dtSearch assembly is not listed. I clicked on the browse button and found the file indicated in by dtsearch and clicked on it. It appears in the New Reference section. I click the Ok button but the reference is not added to my app. Can someone tell me what I am doing wrong?
