Allow strong-named assemblies to be called in shared web hosting environments

Tips

As reported by Aaron Robson, you should use the AllowPartiallyTrustedCallers attribute if you want to allow strong-named assemblies to be called by partially trusted code. This is needed for shared web hosting environments.

Shared hosting environments usually run under a Medium Trust security setting. In Aspnet 2.0 this has changed somewhat, and one of the effects is that any strong named assembly must have the [assembly:AllowPartiallyTrustedCallers] attribute. This is a problem if you're using third party code and they haven't updated it.
One workaround is to set <trust level="full" /> in the web.config file (within system.web element) - although I suspect hosts shouldn't allow this to work.

I will include this in PageMethod's next release. In the meantime, you can use the workaround with the configuration file.

Any idea when that may be ? I was planning to start using PageMethods, the workaround you mention won't work since any host running in medium host will (or at least should) have <location allowOverride="false"> set at the machine level.

Daren, I can make a new release this week-end.

A new version that fixes this problem has just been published.
