Uninstallation of application
<p>i have developed an application in C# which contains the facility of uninstallation. My primary requirement is that when user uninstall the application befor uninstallation start i want to call webservice which perform some operations.</p>

<p>I have return code for this but it works only when user uninstalls application through option given in programms menu. But it not works in the case of uninstallation from Control panel.</p>

<p>how can i do this?
