I have a WCF behavior extension that I would like to add to a WCF client. However, the client is constructed programmatically. The endpoint address may vary, but I know the type. I could add the behavior programmatically or in the config file (preferred), but I need to pass some configuration in the config file only.
I don't want this in Common behaviors (machine.config).
I can add the behavior programmatically
endpoint.Behaviors.Add(new MyCustomBehavior())
But I'd rather do it in config, so I can configure the extension there as well.
Is it possible to declaratively add and configure an endpoint behavior extension to a programmatically constructed endpoint knowing only the the type or interface while leaving the client endpoint to be constructed programmatically?
<system.serviceModel>
<client>
<!-- Created programmatically -->
</client>
<extensions>
<behaviorExtensions>
<add name="MyCustomBehavior" type="namespace.CustomBehaviors", MyAssembly, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null" />
</behaviorExtensions>
</extensions>
<behaviors>
<endpointBehaviors>
<behavior name="MyCustomBehavior">
<MyCustomBehavior MyImportantBehaviorParam1="foo" />
</behavior>
</endpointBehaviors>
</behaviors>
</system.serviceModel>
Of course I could put the config in another section, and have my behavior read it there, but I'd rather use the WCF facilities if possible.
To do that you need to create a behavior configuration extension for your endpoint. For more information on how to do that, check https://learn.microsoft.com/en-us/archive/blogs/carlosfigueira/wcf-extensibility-behavior-configuration-extensions.
Update: I see your issue now. There's no direct way to add to an endpoint created via code a behavior declared in configuration. You can still do it, though, but you'll need to use some reflection to access the
CreateBehavior
method of the behavior configuration extension (the method is protected) to actually create the endpoint behavior to add it to the endpoint created via code. The code below shows how this can be done.And the configuration for this code:
