OK I have created a SAML Implementation using wsFederationHttpBinding but I do not want to encrypt the soap:Body.
As Specified here http://msdn.microsoft.com/en-us/library/system.servicemodel.wsfederationhttpsecuritymode.aspx
it says the "Message Security Mode" will,
By default, the body is encrypted and signed.
How can you turn off the encryption of the Body?
You need to create a custom Binding.
Actually I found an easier way than creating a custom Binding
[System.ServiceModel.ServiceContractAttribute(ConfigurationName="Service.IService",
ProtectionLevel= System.Net.Security.ProtectionLevel.Sign)]
The Protection Level of the Service can tell the wsFederatedHttpBinding weather or not to Sign and Encrypt or just Sign the message.
