Best practice for large WCF service?
That’s been a big question surrounding services since their inception. SOA done successfully is SOA planned to the extent you’re talking about. Having said that, I’ve always leaned more toward splitting services out, but using them in a composite manner. That is, several endpoints when you have several contracts, but most of them are only … Read more
WCF – Inspect the messages being sent/received?
To view the message contents you must add a source for System.ServiceModel.MessageLogging in your configuration file. The message tab in the Trace Viewer will show the full message for a particular service call.

Consequently, the transport security for this binding is designed for seamless interoperation with IIS sites. This is done by setting the security … Read more
WCF error: “The X.509 certificate CN=localhost chain building failed …”
I fixed the problem by turning off validation in my code like this: client.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.None; Where client is an instance of my service reference.
Can WCF Service have constructors?
Out of the box WCF will only use the default constructor, you can’t use parameterised constructors. You have to do a bit of extra work to make WCF call parameterised constructors. You could try this: How do I pass values to the constructor on my wcf service?
What are the differences between security mode=”Transport” and security mode=”TransportCredentialOnly”
Check here: http://developers.de/blogs/damir_dobric/archive/2006/07/31/890.aspx and http://msdn.microsoft.com/en-us/library/ff648505.aspx Transport seems to require HTTPS to encrypt credentials and throws an exception if there is no SSL. TransportCredentialOnly will send the credentials in plain text and unencrypted and is recommended for testing ONLY! Good Luck!!
