Expanding GetExcelFunctions filter condition to include both ExcelFunctionAttribute and ExcelFunctionDocsAttribute ?

[casbby]

Hi

I raised a issue for a conflict between ExcelFunction and ExcelFunctionDoc attribute as both of them include the same property ExplicitRegistration https://github.com/Excel-DNA/ExcelDnaDoc/issues/36

My goal is to use the Registration so I can have default parameter value. However in the Registration.CS the following function stipulates only function with ExcelFunction attribute will be registered. This seems to be a catch 22 situation for me. I am not if this is a real oversight. And if it indeed is do you want to fix here or in the doc gen solution ( which can not support both attribute at the same time otherwise it will fail with System.Reflection.AmbiguousMatchException)

        public static IEnumerable<ExcelFunctionRegistration> GetExcelFunctions()
        {
            return from ass in ExcelIntegration.GetExportedAssemblies()
                   from typ in ass.GetTypes()
                   from mi in typ.GetMethods(BindingFlags.Public | BindingFlags.Static)
                   where mi.GetCustomAttribute<ExcelFunctionAttribute>() != null
                   select new ExcelFunctionRegistration(mi);
        }

Thank you very much casbby
