asp.net 样板 odata 计数

Question

我正在开发 asp.net 支持odata的核心样板应用程序。我正在尝试启用$count参数：

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

请求是：

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

但响应没有计数：

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

如何使用样板 odata 将计数添加到响应中？

附言

为了在结果中获取计数，网址应该是：

/odata/message?$count=true
