When i deploy my app to our server I get the following error thrown. When setting the license key value.

Could not load file or assembly 'Xceed.FileSystem, Version=3.5.7326.14130'
I am compiled against version 3.6.7376.15420 and don't understand why it's looking for another version.

both my local machine and the server have the same exact versions of the Xceed.FileSystem.dll

Any ideas?

string _configXceedLicenseKey = "XceedLicenseKey";
string path = Assembly.GetExecutingAssembly().Location + ".config";
NameValueCollection appSettingCollection;
ConfigurationManager manager = new ConfigurationManager();
Configuration configuration = manager.OpenExeConfiguration(path);

appSettingCollection = configuration.AppSettings.Settings;

Xceed.Ftp.Licenser.LicenseKey = appSettingCollection[_configXceedLicenseKey]; // THIS IS THE LINE THAT THROWS THE ERROR

Are all the necessary .dll included?

Did you redirect your reference to the new .dll? It seems that the application is looking for a different version of the .dll.

I had (almost) the same problem. Im just gonna write here how i solved it, maybe it'll help someone someday...=P

The thing was that when I installed Xceed components to my server machine, I downloaded the latest version from the Xceed
website. In that version the .dll file versions were newer than the ones that were referred in my web.config file. I changed the version numbers to correct one in the web.config and the problem was solved.
