Automatically update a C# Windows Forms application

Question

I want my application to automatically check for updates and update the application if needed. I installed InstallShield Limited edition, but when I went to the update section I found out that I need to install FlexNet which requires me to purchase it.

I found out that Windows has stopped supporting Windows Installer which is why in Visual Studio 2013 it's not listed in the setup and deployment section.

I also read about ClickOnce, but there is a small issue when I tried to deploy my application to the FTP server. It asked for the username and password, but it added a warning that these values will be in plain text! So, what should I do? Is there another third-party way of creating an installer and setting up automatic updates?

Answer 1

I've used ClickOnce with dozens of applications and have never seen the username/password prompt. My process is:

1. Declare the application is downloaded from "http://www.yourSite.com/yourApp/"
2. Publish to folder "yourApp" in whatever location you want
3. Drag and drop that whole folder into your WWW space on your server
4. Email your users the link "http://www.yourSite.com/yourApp/yourApp.application"

For updates, just repeat this same process (except emailing users), and everything else takes care of itself. Be sure check the box in your application settings that tells it to check for updates of course.
