WCF 4–New Feature–Default Configuration

Until recently I had worked only with WCF upto version 3.5. So recently when I came across a configuration file which only had this information in it, I was perplexed to say the very least:

<behavior name="">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

What was missing from the web.config file were the endpoint and behavior definitions. But the service worked correctly. Very perplexing indeed.

And then I found out that in WCF4, the .Net team added a new feature called default configuration. The goal of default configuration was to make it easy to create a basic web-service (as easy as it was to create a web-service using the ASMX file – a .Net 2.0). Which is why the above configuration section doesn’t have any settings for endpoints or behaviors – they are being setup by default configuration.
