Provide Uninstaller for your CSharp(C#) Applications

Most of us will face a common problem, how to Uninstall our programs once it has been Installed. The below code snippet will give you the answer.

This uninstaller program needs an argument the ProductCode. It searches for the ProductCode and remove/repair the application according to the choice X/I provided respectively.
Build this as a seperate console application.
Add this primary output into your setup.
Select your setup and press F4, from the property window select the product code including {} braces let us say "{123abcd45678}" is your product code. Now create short cut for your uninstall program.
Select that shortcut then press F4, to get property window, paste this under Arguments attribute like /u={123abcd45678}.
That's it. Build your setup and deploy. After deployment click your uninstall icon to uninstall your product.

	{
	  string GUID;
	  string sPath;
	  ProcessStartInfo opInfo;
		  
	  try
	  {
		string[] arguments = Environment.GetCommandLineArgs();
		foreach(string argument in arguments) 
		{
			if ((argument.Split("=")[0].ToLower == "/u")) 
			{
			  GUID = argument.Split("=")[1];
			  sPath = Environment.GetFolderPath(Environment.SpecialFolder.System);
			  opInfo = new ProcessStartInfo((sPath + "\\msiexec.exe"), ("/x " + GUID));
			  // use /x to provide remove option only.
			  // use /i to provide uninstall and repair.
			  Process.Start(opInfo);
			}
