Hi

Using ILS in a wpf application (not control), and essentially configuring it as per the wpf authentication sample supplied. The license uses authentication data in the form of Program level, number of days to expiry eg(Enterprise,180). I know that I can alter the authenticated data for a license and that that data gets exported up to the authentication server (on the grounds that when I import the authentication data it shows my amendments).

According to the help file I should then be able to call Reauthenticate in order to get the license updated on the end user machine without their having to uninstall and reinstall the license. So using the basic setup as per the sample application I have the following:

Code:
_license = _licenseProvider.GetLicense()
      _licenseProvider.Reauthenticate(_license, True)


However, no matter how many times I run the application the authenticated data never seems to change. Have I missed something obvious here?

The Reauthenticate method returns the new (updated) license - but you are not using the returned result. It does not actually install the updated license. To Reauthenticate and Install the license you should use the AtomicReauthenticateAndInstallLicense. This method installs the updated license and returns it. Note that you need to handle any possible exceptions (eg WebExceptions due to no internet connection).

If you use the StartBackgroundReathentication method (like the sample projects) then AtomicReauthenticateAndInstallLicense is called automatically on a background thread periodically (you can determine the frequency). However you can still provide an option to the user to reauthenticate immediately and call the method yourself if you want.
