Sharepoint ajax web service compatibality

I have a Sharepoint publishing site that is configured to use ajax 1.0 to use some third party controls (RadEditor, Bamboo).

My problem is I have created a custom web service (.asmx) in a visual studio wspbuilder project and dep开发者_开发技巧loyed it to the ISAPI folder. The project is set up to use .net 3.5 framework. This works fine for our custom code, but I am having issues making calls to the custom web service via the jQuery $.ajax method. All I get back is generic error messages.

My question is can a website that is configured to use ajax 1.0 make a call to a .asmx web service that was compiled using the .net 3.5 framework?

I got this to work, I had to add this to the section of the web.config:

    </dependentAssembly>
