Question

I am struggling to convert a silverlight application from HTTP to HTTPS using the WCF and a self signed certificate registered into IIS.

Calls i have made in the Visual Studio 2010 Command Prompt:

 makecert -sv SignRoot.pvk -cy authority -r signroot.cer -a
    sha1 -n "CN=Dev Certification Authority" -ss my -sr localmachine    

makecert -iv SignRoot.pvk -ic signroot.cer -cy end -pe -n
    CN="localhost" -eku 1.3.6.1.5.5.7.3.1 -ss my -sr
    localmachine -sky exchange -sp
    "Microsoft RSA SChannel Cryptographic Provider" -sy 12

I have this as the end point (this is the call that still is not HTTP in Fiddler)

<!-- Address that the Silverlight clients will connect to -->
<!-- as specified in their web.config -->
<add key="gatewayListeningHttpURI" value="http://localhost:10201/" />

Current Server Config:

        dscc.InnerChannel.OperationTimeout = TimeSpan.FromMinutes(15);
#endif
        return dscc;
    }

I have deployed my silverlight applicatoin into IIS and have added the HTTPS protocol to it so that i can reach it by adding HTTPS in front of the web address.

Problem is still when i log onto the https site (https://localhost/FleetNew), I Still recieve the error of “Display MIxed Content”

When i watch in fidler, it is the call localhost:10201 that is the unsecure http call.

my netsh http show sslcert command brings me this:

IP:port                 : 0.0.0.0:10201

Please help me configure this correctly so that the call to locahost:20102 will work over ssl and HTTPS

Answer 1

Well from what I can tell you are missing several of the HTTPS metadata endpoint and behavior configurations necessary for hosting a WCF self-hosted service using SSL. The main steps to do what you need are the following:

1. Create a self-signed certificate (for testing purposes) with a matching common name value of the domain name of your endpoint URL (best to use your machine name)
2. Use netsh.exe to bind the port with your SSL certificate using it’s thumbprint.
3. Configure your WCF .config file to have the required SSL settings.

This is a rather lengthy process so rather than try and document every step here, I have a blog post that details what you need to get your WCF self-hosted service using SSL. This should help you see a working solution that you can then apply to your project:
