SoapExtension in current assembly causes compile error under ASP.N

[Symon]

I've got a web service project that was built under VS 2003 which has a
SoapExtension in the project. The SoapExtension is registered in the
<soapExtensionTypes> element of the web.config and has worked fine for some
time.

Recently we tryed to update the project to VS 2005 and run it under ASP.NET
2.0, but now we get a compile time exception:

"The value of the property 'type' cannot be parsed. The error is: Could not
load file or assembly 'TheWebService' or one of its dependencies. The system
cannot find the file specified."

The registration of the SoapExtension in the web.config is like this where
TheWebService is the name of the web service application and
SecurityExtension is the SoapExtension class in the TheWebService namesapce:

<soapExtensionTypes>
<add type="TheWebService.SecurityExtension, TheWebService" priority="1"
group="high"/>
</soapExtensionTypes>

The code has not changed and I'm guessing that this is due to changes in the
way that ASP.NET handles it's compilation.

Is it no longer possible to register a SoapExtension that is in the current
assembly for a web service? I *really* don't want to move the extension out
to another assembly.

Hoping someone out there can provide a hint on this.

Cheers,

Symon.
