Using the Custom ServiceHostFactory in a WCF Services Library Project

Question

I program the WCF service, which depends a lot on the inverse of the control. I would like to load or initialize my IoC container inside a custom ServiceHostFactory. I read a few examples of the various hooks available, but none of them seem to work for me.

This approach is the one I would prefer to use (custom IServiceBehavior, IInstanceProvider, ServiceHost and ServiceHostFactory), but the last step is a signal to the service to use my custom service ServiceHostFactory inside my * .svc file of the serivce file. I do not have one of them, since the project type is a WCF service library, not a WCF service service. Is there a way WCF can use my ServiceHostFactory in the App.config file?

Answer 1

Since I do not see anwer, I will post what I found, which is not very encouraging.

All links to ServiceHostFactory point to the svc file and the Factory attribute, which is not what you are looking for.

This thread on MSDN even says that it is not possible to accomplish what you are trying to achieve.

Unfortunately...

Ciddan, glad to see you found a resolution (albeit not ideal). I had the same question as you, and finally decided to use IIS to host the service and connected my custom Ioc classes (which are in my WCF Service Library) using the serviceHostingEnvironment service in my web.config. Something like that:

<serviceHostingEnvironment multipleSiteBindingsEnabled="true"> <serviceActivations> <add relativeAddress="./Service1.svc" service="WcfServiceLibrary1.Service1" factory="WcfServiceLibrary1.IocServiceHostFactory, WcfServiceLibrary1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> </serviceActivations> </serviceHostingEnvironment> 

"./Service1.svc" is my file service, where WcfServiceLibrary1.Service1 is a specific imp. I hit a few stumbling blocks, but eventually managed to encapsulate Ioc from the WCF Service Library.
