title: Working with DirectoryServices in ASP.NET Core
body: <p>I am upgrading my ASP.NET Core RC1 application to RC2. I have some references to <code>System.DirectoryServices</code> and <code>System.DirectoryServices.AccountManagement</code> in some *.cs files so that I can query LDAP. But I have no idea how to add references to it in RC2 in the <code>Project.json</code> file. Everything that I try just gives me more errors. Any help is appreciated.</p>
