从 .net 4.6.2 azure service fabric 有状态程序集调用 .Netstandard dll

Question

我正在努力从 Visual Studio 2017 [在 Windows 7] 中的 .Net 4.6.2 azure service fabric statefulservice 程序集中调用 .netstandard dll。我正在使用最新版本的服务结构 [5.4.164.9494 和 SF SDK 版本：2.4.164.9494]

按照Using .net standard 1.5 lib in .net 4.6.2 misses System.Runtime 4.1.0.0 中提到的确切步骤进行操作。尝试了多种方法，例如从 .Net 核心、.Netstandard 和普通的旧 PCL（从项目属性转换为 .net 标准）创建 netstandard 类库。没有任何效果。该项目确实编译但是当我将项目部署到集群时，有状态服务永远不会被初始化，这是日志中的错误..

您是否正在使用 Windows Server 2012R2 或 2016 运行 SF 集群？ Azure 门户的默认选项仍然是 2012R2，并且只有 .NET 4.5.1，除非您自己安装 4.6.2（手动或通过脚本）
