How to mark COM Visible for auto generated c-sharp class?

James J 586

I am in process of adding webView browser control to launch the Javascript. Javascript makes SOAP call through C# interop class. But, the wsdl associated c# reference file is auto generated. To communicate JS and Webview the c# class should be COM visible. The question here is, How I can mark COM visible for auto generated C# class?

Thanks

@James J , Welcome to Microsoft Q&A, could you provide your generated class and related interface?
As usual, you could try the following code to mark COM visible:

[Guid("4794D615-BE51-4a1e-B1BA-453F6E9337C4")] [ComVisible(true)] [ClassInterface(ClassInterfaceType.None)] [ComSourceInterfaces(typeof(IComEvents))] public class MyComObject : IComObject { }

For a auto generated class you could implement a a partial class that conforms to the basic COM specs in addition to the answer of JackJJun-MSFT
AFAIK one of the requirements of a COM / ActiveX object is also that it should have a default constructor.
