How do i specify wcf behaviorExtension class type without the assembly version number?

Question

I have a web app that uses a WCF service that utilizes a behaviorExtension like so:

<behaviorExtensions>
<add name="clientCredentialsExtension" type="Simon.Web.Giftcard.WCFSecurity.ClientCredentialsExtensionElement, Simon.Web.Giftcard, Version=1.0.3736.20411, Culture=neutral, PublicKeyToken=null"/>
</behaviorExtensions>

The problem is this web app's version changes with every compile (i think) and thus invalidating this entry.

How can I avoid having to change the version number every time I compile this? Can I specify the extension in code somewhere?

Answer 1

Try this:

<behaviorExtensions>
    <add 
        name="clientCredentialsExtension"         
        type="Simon.Web.Giftcard.WCFSecurity.ClientCredentialsExtensionElement, Simon.Web.Giftcard"/>
</behaviorExtensions>

Answer 2

If you are stuck with .NET 3.5 where the configuration bug is not fixed yet, the solution is to implement IServiceBehavior by your service. See this article, example 6-15 .

Answer 3

Apparently it's fixed in .Net 4.0 beta 2. Not much use to me, who is stuck with 3.5.

Answer 4

This annoying bug bit me before too. I eventually changed all mine to build up in code instead of in the config.
