asp.net boilerplate odata count

Question

I'm developing asp.net core boilerplate application with odata support. I'm trying to enable $count parametr:

app.UseOData(builder =>
            {
                builder.EntitySet<Message>("Messages").EntityType.Count().Filter().OrderBy().Expand().Select().Page().Count();//.Expand().Filter().OrderBy().Page();
            });

and request is:

/odata/Messages?%24count=true&%24filter=indexof(tolower(Guid)%2C+%27a3eee6ec-d232-42f7-93cc-fd6062fb39b6%27)+gt+-1

but response has no count:

{
"result": [
{
"guid": "a3eee6ec-d232-42f7-93cc-fd6062fb39b6",
"id": 140
}
],
"targetUrl": null,
"success": true,
"error": null,
"unAuthorizedRequest": false,
"__abp": true
}

How to add count to response with boilerblate odata?

要在结果中计数，网址应为：

/odata/message?$count=true
