WCF 转到 .NET5 相同的类型无法转换

Question

原的来服务用WCF写的现在转到 .NET5,原来没有问题的代码出问题了

代码

this.pModule = (Aw.Y4.Svc.ApplicationService.ApplicationService)mmmm;

异常

System.InvalidCastException:

[A]Aw.Y4.Svc.ApplicationService.ApplicationService
cannot be cast to
[B]Aw.Y4.Svc.ApplicationService.ApplicationService.

Type A originates from 'Aw.Y4.Svc.Y45Service, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location '/var/opt/y4service/Aw.Y4.Svc.Y45Service.dll'.
Type B originates from 'Aw.Y4.Svc.Y45Service, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location '/var/opt/y4service/Aw.Y4.Svc.Y45Service.dll'.

完全一样的东西，不能转换？

由于.NET 5是跨平台框架，而WCF仅针对windows操作系统，所以你需要考虑 WCF的替代方法：
