有趣的错误，请考虑将其发布到EF Core GitHub问题跟踪器。
根据想法，你尝试过的应该做
modelBuilder.Entity<SystemUser>()
.HasMany(x => x.LogBooks)
.WithMany(x => x.SystemUsers)
.UsingEntity<Dictionary<string, object>>("LogBookSystemUsers",
x => x.HasOne<LogBook>().WithMany().HasForeignKey("LogBookId"),
x => x.HasOne<SystemUser>().WithMany().HasForeignKey("SystemUserId"),
x => x.ToTable("LogBookSystemUsers", "LogBooks"));
它适用于任何其他FK属性名称，但{RelatedEntity}Id调用关联实体PK属性的时间除外ID。
作为解决方法，直到它得到解决，在配置关系之前，先明确定义所需的联接实体属性：
// add this
modelBuilder.SharedTypeEntity<Dictionary<string, object>>("LogBookSystemUsers", builder =>
{
builder.Property<int>("LogBookId");
builder.Property<int>("SystemUserId");
});
// same as the original
modelBuilder.Entity<SystemUser>()
.HasMany(x => x.LogBooks)
.WithMany(x => x.SystemUsers)
.UsingEntity<Dictionary<string, object>>("LogBookSystemUsers",
x => x.HasOne<LogBook>().WithMany().HasForeignKey("LogBookId"),
x => x.HasOne<SystemUser>().WithMany().HasForeignKey("SystemUserId"),
x => x.ToTable("LogBookSystemUsers", "LogBooks"));

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.

谢谢！效果很好，只是告诉我我需要一个钥匙，所以我必须添加一个钥匙：
builder.HasKey("LogBookId", "SystemUserId");EF Core 5.0.2版中已修复此问题。我原来的解决方案现在可以正常工作了。
