我有azure云服务项目，每当我尝试构建或运行时，我都会收到以下错误

`The "DeleteCurrentDeployment" task failed unexpectedly.

我多次卸载VS 2017并再次安装它仍然无法正常工作并出现同样的错误，有人可以帮忙吗？

可以解决问题......经过大量的分析。这是由于损坏的DevFabric.config文件

尝试从天蓝色模拟器工作的机器（来自同一路径）替换C：\ ProgramData \ dftmp \ DevFabric.config

VS 2017 Azure计算模拟器异常System.Runtime.Serialization.SerializationException
