Hi,

It is 99% sure that something is missing in your provider code.

Without having access to your code, I cannot tell what exactly the problem is.

I assume you have a Dynamicweb solution running on your development machine, which you are using to test.

If you add the lines:

Debugger.Launch();

Debugger.break();

You should be able to step through and debug until you find the error in your code that is causing the problem.

It is most likely in either your LoadSettings() method, or one of the GetSchema/OverrideSchema methods, since the problem appears when the provider is being loaded from the XML file. I recommend starting with debugging in these methods.

Hi Jonas,

Thank you very much!

Now I found out what went wrong.

I misspelled the node.Name.

Best Regards.
