EF Core：无法翻译 LINQ 表达式 - Net Core 3.1

Question

我正在尝试执行查询以查找每个站点中与指定用户的条件匹配的所有条件并删除它们 - 排除不匹配的条件。

var savedPartnerConditions = eipDbContext.EIP_User_Partner_Condition.Where(savedCondition => savedCondition.EIP_User_Partner_Id == savedPartner.EIP_User_Partner_Id && existingUser.CurrentUserConditions.Any(condition => condition.Code == savedCondition.Code));

eipDbContext.EIP_User_Partner_Condition.RemoveRange(savedPartnerConditions);

但无法翻译查询，导致出现以下错误：

.Any(condition => condition.Code == e.Code))' could not be translated. Either rewrite the query in a form that can be translated, or switch to client evaluation explicitly by inserting a call to either AsEnumerable(), AsAsyncEnumerable(), ToList(), or ToListAsync()

如何构造查询来修复错误？

我能够使用以下似乎有效的代码解决此问题：

var selectionResultSet = eipDbContext2.EIP_User_Partner_Condition.Where(savedCondition => savedCondition.EIP_User_Partner_Id == savedPartner.EIP_User_Partner_Id).ToList();

var savedPartnerConditions = selectionResultSet
.AsEnumerable()
.Where (savedCondition => (existingUser.CurrentUserConditions.Any(condition => condition.Code == savedCondition.Code)));

eipDbContext3.EIP_User_Partner_Condition.RemoveRange(savedPartnerConditions);
