EF Core 5 多对多关系 - 更改导航键

Question

我有两个在 EF Core 5 中具有多对多关系的实体，我正在使用流利的 API 来设置关系。

public class Framework
{
    [Key]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public long Id { get; set; }

    [Required]
    public string Name { get; set; }

    public IList<Path> Paths { get; set; } = new List<Path>();
}

public class Path
{
    [Key]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public long Id { get; set; }

    [Required]
    public string Name { get; set; }

    public IList<Framework> Frameworks { get; set; } = new List<Framework>();
}

protected override void OnModelCreating(ModelBuilder builder)
{
      base.OnModelCreating(builder);

      builder.Entity<Framework>()
          .HasMany(x => x.Paths)
          .WithMany(x => x.Frameworks)
          .UsingEntity<Dictionary<string, object>>(
              "FrameworkPaths",
              x => x.HasOne<Path>().WithMany(),
              x => x.HasOne<Framework>().WithMany(),
          );

工作正常，正在多对多 table 中添加数据（其中包含这些列 FrameworksId、PathsId)

但现在我想将 Path 实体中的属性名称从 Frameworks 更改为 LinkedFrameworks 作为

public IList<Framework> LinkedFrameworks { get; set; } = new List<Framework>();

如何在实体的 CRUD 操作中使用这个新的属性名称 LinkedFrameworks 而不是 Framework？

通过在usingEntity中添加.HasForeignKey()实现

builder.Entity<Framework>()
                .HasMany(x => x.Paths)
                .WithMany(x => x.LinkedFrameworks)  //Change the name here
                .UsingEntity<Dictionary<string, object>>(
                    "FrameworkPaths",
                    x => x.HasOne<Path>().WithMany(),
                    x => x.HasOne<Framework>().WithMany().HasForeignKey("FrameworksId")); //tell the EF about the Foreign Key
