this is what i got from support team.

Hello Muhammad,

We have escalated and fixed this issue in an effort to provide you with a fix as quickly as possible.

This fix is not a full-fledged service release.  It has been provided to you outside of standard procedures.  It has not gone through standard Quality Assurance regression testing or installer testing, and therefore there is heightened risk associated with its use.  We have verified that this fix addresses your specific development issue.

With this in mind, please ensure that you fully back up your application, along with all currently installed NetAdvantage .NET assemblies, before installing this fix and upgrading your project.  Please fully test all aspects of your application to ensure that there are no unexpected results.  If you do find an issue, please provide us with the details so we can assess and address it.  Please also let us know if everything appears to be acceptable and no issues are exposed.
