注解

如果未找到匹配的属性，则关系不表示所有权，依赖方不明确且不派生，如果关系是一对一的，则使用主键属性;否则，如果属性是依赖 PK 的正确子集，则约定会尝试将具有确切名称的属性匹配为主体键属性。

如果找到了匹配项，但属性类型与主体键类型不兼容，则不会搜索进一步的匹配项。

如果关系使用按约定创建的阴影属性，则重新创建它们以删除用于使名称唯一的后缀。

有关详细信息和示例，请参阅模型生成约定。

ProcessEntityTypeMemberIgnored(IConventionEntityTypeBuilder, String, IConventionContext<String>)	在忽略实体类型成员后调用。
ProcessEntityTypePrimaryKeyChanged(IConventionEntityTypeBuilder, IConventionKey, IConventionKey, IConventionContext<IConventionKey>)	在实体类型的主键更改后调用。
ProcessForeignKeyAdded(IConventionForeignKeyBuilder, IConventionContext<IConventionForeignKeyBuilder>)	在将外键添加到实体类型后调用。
ProcessForeignKeyAdded(IConventionRelationshipBuilder, IConventionContext<IConventionRelationshipBuilder>)	在将外键添加到实体类型后调用。
ProcessForeignKeyPrincipalEndChanged(IConventionForeignKeyBuilder, IConventionContext<IConventionForeignKeyBuilder>)	在外键的主体末尾更改后调用。
ProcessForeignKeyPrincipalEndChanged(IConventionRelationshipBuilder, IConventionContext<IConventionRelationshipBuilder>)	在外键的主体末尾更改后调用。
ProcessForeignKeyPropertiesChanged(IConventionForeignKeyBuilder, IReadOnlyList<IConventionProperty>, IConventionKey, IConventionContext<IReadOnlyList<IConventionProperty>>)	在更改外键属性或主体键后调用。
ProcessForeignKeyPropertiesChanged(IConventionRelationshipBuilder, IReadOnlyList<IConventionProperty>, IConventionKey, IConventionContext<IConventionRelationshipBuilder>)	在更改外键属性或主体键后调用。
ProcessForeignKeyRequirednessChanged(IConventionForeignKeyBuilder, IConventionContext<Nullable<Boolean>>)	更改外键的必需项后调用。

ProcessKeyRemoved(IConventionEntityTypeBuilder, IConventionKey, IConventionContext<IConventionKey>)	这是一个支持 Entity Framework Core 基础结构的内部 API，不受与公共 API 相同的兼容性标准的约束。可能会在任何版本中更改或删除它，恕不另行通知。应仅在代码中直接使用它，并且非常谨慎，并且知道在更新到新的 Entity Framework Core 版本时，这样做可能会导致应用程序失败。
ProcessModelFinalized(IConventionModelBuilder, IConventionContext<IConventionModelBuilder>)	这是一个支持 Entity Framework Core 基础结构的内部 API，不受与公共 API 相同的兼容性标准的约束。可能会在任何版本中更改或删除它，恕不另行通知。应仅在代码中直接使用它，并且非常谨慎，并且知道在更新到新的 Entity Framework Core 版本时，这样做可能会导致应用程序失败。
ProcessModelFinalizing(IConventionModelBuilder, IConventionContext<IConventionModelBuilder>)	在最终确定模型时调用。
ProcessNavigationAdded(IConventionNavigationBuilder, IConventionContext<IConventionNavigationBuilder>)	在将导航添加到实体类型后调用。

ProcessPropertyNullabilityChanged(IConventionPropertyBuilder, IConventionContext<IConventionPropertyBuilder>)	在属性的可为 null 性更改后调用。
ProcessPropertyNullabilityChanged(IConventionPropertyBuilder, IConventionContext<Nullable<Boolean>>)	在属性的可为 null 性更改后调用。
ProcessSkipNavigationForeignKeyChanged(IConventionSkipNavigationBuilder, IConventionForeignKey, IConventionForeignKey, IConventionContext<IConventionForeignKey>)	在跳过导航逆向更改后调用。
ProcessSkipNavigationInverseChanged(IConventionSkipNavigationBuilder, IConventionSkipNavigation, IConventionSkipNavigation, IConventionContext<IConventionSkipNavigation>)	在跳过导航逆向更改后调用。
