Get reference dll into another dll which is exposed to COM <p>I'm want to find the answers for this problem:</p> <p>I'm developing a .NET 4.0 DLL wich has reference to another third party Dll FTP. This DLL that i'm developing is loaded through reflection by another DLL called LoaderDLLs.</p> <p>LoaderDLLs is exposed for COM, the problem is when the COM use DLL to invoke .NET DLL 4.0 everything is fine but when .NET DLL 4.0 internally call third party DLL FTP occurs next error:</p> <p><strong>Exception has been thrown by the target of an invocation.Could not load file or assembly 'Jscape.Ssh, Version=2.7.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.</strong> </p> <p>I have attemped install third party DLL FTP into GAC through gacutil, but a think this is not working, How can i get reference to that DLL?</p>
