WCF binding error

So I got into work early today and got the latest from source control. When I try to launch our ASP.NET application, I get this exception:

"The binding at system.serviceModel/bindings/wsHttpBinding does not have a configured binding named 'wsHttpBinding_Unsecured_Long'. This is an invalid value for bindingConfiguration. (C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Config\machine.config line 789)"

Nobody's here at work yet so I can't get any help on this. What the heck does this mean--can someone try to briefly explain it to me, and can I fix it? (I work on the 开发者_如何学编程front-end side and this looks related to the WCF services we have, so I'm not familiar.)

Sounds like your IT department pushed out some changes to the machine.config file which are bad.

It is a problem with your WCF configuration. An end point my be pointing to a binding configuration that is not defined.

Agree with Drew. You have an endpoint that is using a bindingconfiguration that does not exist.

Just wanted to add that that type of configuration does not belong in the machine config.
