A library of core helpers, extensions, constants, enums and other useful things for .NET WCF projects.
Install-Package CoreWcf
The CoreWcf assembly contains all you need to add CORS support to WCF endpoints. It contains the classes described here, so add the web.config changes as described using
<add name="crossOriginResourceSharingBehavior" type="CoreWcf.Behaviors.EnableCrossOriginResourceSharingBehavior, CoreWcf" />
as the new behaviour.
