[wix-users] WIX does not remove the web applications after uninstall

[santhosh yalamuri]

We are using WIX 3.10 to create web applications under default website, this implementation works fine but the issue is with uninstall of the product that it does not remove the web application under the default website.
The Website port and name are entered by user as part of custom dialog which are stored in respective properties.further during uninstall these properties are restored using wix toolset remember property http://robmensching.com/blog/posts/2010/5/2/the-wix-toolsets-remember-property-pattern/ which sets the web application property during uninstall, but still the application is not removed on uninstall.
Uninstall log that sets the website properties after Appsearch:
Action start 15:17:04: AppSearch.

There is another issue related, repair operation through Add Remove Programs throws a Fatal error with the following error:
WriteIIS7ConfigChanges: Entering WriteIIS7ConfigChanges in C:\Windows\Installer\MSICDDF.tmp, version 3.10.3007.0
WriteIIS7ConfigChanges: Custom action data hash: 41034C345A4E6B9B4DDB8490C1BC5266637BC0E8

WriteIIS7ConfigChanges: Error 0x80070002: Site not found for create application
WriteIIS7ConfigChanges: Error 0x80070002: Failed to configure IIS application.
WriteIIS7ConfigChanges: Error 0x80070002: WriteIIS7ConfigChanges Failed.
Any other alternative solution that would solve the issue?
