IIS Express & SSL

  • Gérald Barré

IIS Express is a version of IIS that is optimized for developers. This version does not provide all the features of IIS, but it is often sufficient to develop a web application.

IIS Express is used by default by Visual Studio to host sites during development. By default, the site uses the HTTP protocol. For some sites, it is necessary to use the HTTPS protocol (for example to use third-party resources). In order to use this protocol, you must activate it explicitly.


  1. Select the project in solution explorer
  2. Show the Properties pane (F4)
  3. Set SSL Enabled to true
