Please look at my code below and let me know where I’m going wrong. This code is not working to reorder a list’s content type order using CSOM.

List aeList = context.Web.Lists.GetByTitle(“Events and Announcements Demo1”); ContentTypeCollection oContentTypes = aeList.ContentTypes;
Folder rootFolder = aeList.RootFolder; ContentType[] orderedContentTypes = new ContentType[1];

        foreach (ContentType oContentType in oContentTypes)         {             if (oContentType.Name == "Events and Announcements")             {                 orderedContentTypes[0] = oContentType.Id;                 rootFolder.UniqueContentTypeOrder = orderedContentTypes[0]; /*I'm receiving Cannot implicitly convert type 'Microsoft.SharePoint.Client.ContentType' to 'System.Collections.Generic.IList<Microsoft.SharePoint.Client.ContentTypeId>'   error here*/                  rootFolder.Update();                 context.ExecuteQuery();             }         }         Console.WriteLine("Events and Announcements content type is set to default");
