c# - 不能将 $count 与 ODataRoute 属性一起使用

Question

使用ODataRoute属性会使$count不起作用。

/// Startup.cs
app.UseOData("odata", "odata", GetEdmModel());

static GetEdmModel()
{
    ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
    builder.EntitySet<User>("User");
    builder.EntitySet<User>("Product");
    return builder.GetEdmModel();
}

/// MyController.cs
[EnableQuery]
[ODataRoute("User")]
public IQueryable<User> GetUser() => User.GetQuery());

[EnableQuery]
[ODataRoute("Product")]
public IQueryable<Product> GetProduct() => Product.GetQuery());

http://localhost:5901/odata/User（工程）
http://localhost:5901/odata/User/$count（不工作）

我认为将 AllowedQueryOptions 添加到EnableQuery属性可能会有所帮助

[EnableQuery(AllowedQueryOptions = AllowedQueryOptions.All )]
[ODataRoute("User")]
public IQueryable<User> GetUser() => User.GetQuery());
