WCF-Custom Send Port MutualSSL with WS-Security

I had to define a WCF send port connecting to a service that used mutual SSL and Web Service Security. I had to use a WCF-Custom send port because the service was using Soap 1.1, not Soap 1.2. In the latter case I could have used a WCF-wsHttp binding.

Before creating the BizTalk send port, make sure the following prerequisites are set:
– The client certificate (with private key, i.e. pfx certificate) is installed in the LocalMachine / Personal Store.
– Right click the certificate. Select All Tasks / Manage Private Keys. Add te BizTalk Application Users group and give them full control rights.
– The server certificate (with public key, i.e. cer/crt certificate) is installed in the LocalMachine / Trusted People Store.

Now create a BizTalk sendport and select WCF-Custom.

Configure the WCF-Custom adapter:

• Address: https://…
• BtsActionMapping: http://www.stichting-vera.nl/StUF/verticaal/woonruimteverdeling/0301/wrveenLk01 (in this case we only have one operation)
  Alternative:
  <BtsActionMapping xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xmlns:xsd=”http://www.w3.org/2001/XMLSchema”>
