How to make running application to uninstall itself?

  • Article

Today I had this requirement. The application that running in windows mobile has to uninstall itself. So started thinking in this lines.

Will windows mobile allow me to uninstall a running application? Even if it does can the application uninstall itself.  After spending 20 - 30 mins in MSDN, I found out that uninstall CSP can do this job. Once the request is submitted to the Configuration manager, it does what you want. Below is the function that I have written to cater this requirement.

private void UninstallThis()
{
 XmlDocument xmlDoc = new XmlDocument();
 StringBuilder sb = new StringBuilder();
 sb.Append("<wap-provisioningdoc> ");
 sb.Append("<characteristic type=\"UnInstall\">");
 sb.Append("<characteristic type=\"Sample Application\">");
 sb.Append("<parm name=\"uninstall\" value=\"1\"/>");
 sb.Append("</characteristic>");
 sb.Append("</characteristic>");
 sb.Append("</wap-provisioningdoc>");
 xmlDoc.LoadXml(sb.ToString());
 ConfigurationManager.ProcessConfiguration(xmlDoc, false);
}
