Question

将我的项目更新为1.1.1后，以下两行不起作用： var d = new FileStream(Path.Combine(PathToFile, $"{fileName}.txt"), FileMode.Open); var fs = new StreamReader(d,Encoding.UTF8);

当我将chane恢复为csproj文件时，错误消失了。我做错了什么？

我收到以下错误：

错误CS0433“System.IO，Version = 4.1.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a”和“System.Runtime.Extensions，Version = 4.2.0.0，Culture = neutral”中存在“StreamReader”类型公钥= b03f5f7f11d50a3a'

@ericwj据网络工具团队的乔，这是一个已知问题。有一个版本的BrowserLink包有错误的引用，而显然是随.NET Core 1.1 CLI安装程序一起提供的。但是，在RC.3中，我们从Core 1.1模板中删除了BrowserLink，因此它不应该是新项目的问题。

Answer 2

在我的情况下，这是在安装SPA模板后发生的。我不得不修复视觉工作室，以便它可以修复版本。
