WebMethod in a Plug-in

[Alphamacaroon]

All,

I have a situation where I want to expose a webmethod from a plugin
that gets loaded dynamically at the startup of a windows service. The
basic architecture looks like this:

Assembly With WebMethod o-------o Windows Service Which Loads Plugin
<-------- {Remoting} ---------IIS

Since IIS will have no clue of the actual assembly with the WebMethod
since it is loaded dynamically and could be located on a completely
different server, it can't easily expose this through the normal .ASMX
route.

So I've created an IHttpHandler which will read the SOAP request and
send this as a string to the windows service which will then parse the
request, call the function on the plug-in assembly, generate a SOAP
response and return it to IIS to write it out in the response.

My issue is that I can't easily find a way to parse the incoming SOAP
request on the service and return a SOAP response. I know I could
parse/generate the SOAP XML myself, but I really don't want to spend
hours doing this if there is an easier way. I've tried using the
SoapFormatter class, but I always get assembly reference errors when I
try to deserialize and invalid SOAP when I serialize the response so
I'm thinking I'm barking up the wrong tree with that one.

Are there any other better/easier ways to do this?

Perhaps I can rephrase the question in a different way:

Is there an easy way to programmatically expose a SOAP WebMethod at
runtime, from a DLL that has been loaded at startup?
