然后包括在.NET核心中不起作用的条件 [英] Theninclude with condition not working in .NET core

问题描述

var cert = _context.Certificates
             .Include(c => c.Staff)
             .ThenInclude(c => c.Department.Abbr.Contains("cs"))
             .Where(c => (int)c.CertificateType == 1)
             .AsNoTracking();

ThenInclude给出错误，因为表达式应代表.net核心中的访问属性。



什么我试过了：



上面的代码没有给出语法错误。但是在运行它时不起作用。

ThenInclude gives error as the expression should represent a property for access in .net core.

What I have tried:

The above code does not give syntax error. But while running it does not work.

推荐答案

如果你不知道的话，你应该把Google错误消息给你...

它你似乎只是在这里遇到一个已知问题：
