.NET Core 3-实体框架客户端评估

Question

在.NET Core 2中，下面显示的代码完美运行，在.NET Core 3和实体框架中，它失败了。我已经看过此链接，但是我无法确定它到底对什么感到不满意，或者为什么它评估不正确。

Evaluation of queries

PersistenceManager.Context
                  .Message.AsNoTracking()
                  .Where(x => roles.Contains(x.BusinessId.ToString())
                              && x.Direction == "IN" && x.IsRead == false 
                              && x.Date >= date)
                 .GroupBy(r => r.ClientId)
                 .Select(g => g.OrderByDescending(p => p.Date)
                               .FirstOrDefault())
                 .Include("Client");

服务器输出的问题似乎是：

source: NavigationTreeExpression
        Value: default(IGrouping<Nullable<Guid>, Message>)
        Expression: (Unhandled parameter: e),
    keySelector: (p) => p.Date))' by 'NavigationExpandingExpressionVisitor' failed. 
This may indicate either a bug or a limitation in EF Core. See https://go.microsoft.com/fwlink/?linkid=2101433 for more detailed information.
