我正在使用Nuget的Microsoft.Bcl.Async软件包构建C＃Windows服务。
一切都很好，但是当我尝试将它安装在一台机器上（XP或Win7＆lt; - 只有.NET 4.0）时，我收到1001错误。这是使用InstallUtil OR InstallShield 2013 LE和安装程序类。
我启用了Fusion日志记录，这是它失败的部分：

我甚至尝试从头开始构建服务并立即安装Microsoft.Bcl.Async以结束相同的结果。
我没有引用不同版本的System.Threading.Tasks。它位于我的服务的bin目录中。我已经冲了几天试图解决这个问题而且我很茫然。
编辑：奇怪的是，我可以从项目中删除所有“异步”和“等待”关键字，现在使用任何异步扩展，如'StreamWriter.WriteLineAsync（）;并将项目中的引用保留为Microsoft.Bcl.Async，该服务将安装正常。一旦我尝试在我的代码中使用'async'或'await'就是我开始遇到这些问题的时候。
