How to Configure IIS Express to Accept SSL Client Certificates
Developing applications with SSL client certificates are a challenge because there are so many little things that can go wrong. You quickly want to open the debugger, but that can be a challenge in itself, especially when the whole chain only works on a remote server. A much simpler way is to use IIS Express with a configuration that accepts SSL client certificates. This setup allows you to debug your application on your local machine without the need to configure the full IIS – at least as long as the errors are in your application.
