如何在实体框架核心中将包含添加到非聚集索引

Question

我有以下实体：

public class ProductInventory
  {
    /// <summary>Gets or sets the product inventory identifier.</summary>
    /// <value>The product inventory identifier.</value>
    public long ProductInventoryId { get; set; }

    /// <summary>Gets or sets the name.</summary>
    /// <value>The name.</value>
    public string Name { get; set; }

    /// <summary>Gets or sets the axis calibration.</summary>
    /// <value>The axis calibration.</value>
    public double AxisCalibration { get; set; }

    /// <summary>Gets or sets the description.</summary>
    /// <value>The description.</value>
    public string Description { get; set; }

    /// <summary>Gets or sets the create date.</summary>
    /// <value>The create date.</value>
    public DateTimeOffset CreateDate { get; set; }
  }

我需要为Name创建一个非聚集索引，并包括以下属性：AxisCalibration，Description。

您可以使用ForSqlServerInclude：

modelBuilder.Entity<ProductInventory>().HasIndex("Name").ForSqlServerInclude("AxisCalibration", "Description");

ForSqlServerInclude在最新的预览版本3.XXX中可以正常工作。
