WCF Service Library vs Class Library project types

Question

What does a WCF Service Library do that a regular class library doesn't?

Edit: I posted my own answer. Am I missing anything? Are they fundamentally both just class libraries with a few template classes added?

Answer 1

I created both and compared. This is what I found.

WCF Service Library

• adds references to System.Runtime.Serialization and System.ServiceModel. does not contain a reference to System.Data.DataSetExtensions as the Class Library does.
• contains sample service classes IService1, CompositeType and Service1
• adds app.config with a wsHttpBinding and a mexHttpBinding service endpoint
• adds /client:"WcfTestClient.exe" as a debug command line option in the project properties
• adds a WCF Options tab in the project properties. This tab contains an option to start a WCF service host when debugging another project in the same solution
• enables a Sign the ClickOnce manifests option in the Signing tab of the project properties. this option is disabled in the Class Library
