Service Fabric远程处理异常->从v1升级到v2

问题描述

我们有一个应用程序已经在Service Fabric上运行了一段时间，并使用无状态服务进行远程处理。升级到Remoting v2后，某些方法失败，并显示以下错误：

system.invalidOperationException: 'Type 'System.String[]' cannot be added to list of kNown types since
 another type 'System.Collections.Generic.IEnumerable`1[System.String]' with the same data contract name 
'http://schemas.microsoft.com/2003/10/Serialization/Arrays:arrayofstring' is already present. If there
 are different collections of a particular type - for example,List<Test> and Test[],they cannot both be 
added as kNown types.  Consider specifying only one of these types for addition to the kNown types list.'

解决方法

我相信您在使用远程v2时遇到了existing issue。 V2要求将“远程处理Api类型”设置为具体类型。

• 在合同中不要使用string[]，而要使用IServiceRemotingMessageSerializationProvider。
• 或提供.rowClassName1 td:first-child { border-top-left-radius: 10px; border-bottom-left-radius: 10px; } .rowClassName1 td:last-child { border-top-right-radius: 10px; border-bottom-right-radius: 10px; } 的{​​{3}}实现
