A soap header may specify a "must understand" flag. This instructs any processing node to throw an exception if this header is not understood by it. Such a behavior is sometimes useful and sometimes very annoying, depending on the circumstances. Let's see how such header looks like in soap:


By default a Wcf service will validate all incoming mustUnderstand headers a client sends. If it does not understand them it will throw the famous 'Did not understand "MustUnderstand" header' exception. Typically you would instruct Wcf not to validate these headers like this:


But this kind of "hard codes" this behavior to the service. Wouldn't it be nice to decide at the configuration level if we want such a behavior or not?

All we need to do is define this class:


Then in the config register it:


And we can now configure our endpoint(s) with this behavior:
