C# VS2017.Net Core 2.0测试：；未能初始化客户端代理：无法连接到测试进程；

我无法从控制台、测试资源管理器或Resharper的测试运行程序在我的计算机上运行任何.Net核心测试

我试图通过创建一个超级基本的测试项目将其分解到尽可能低的级别

项目文件：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
    <IsPackable>false</IsPackable>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.3.0-preview-20170628-02" />
    <PackageReference Include="xunit" Version="2.2.0" />
    <PackageReference Include="xunit.runner.visualstudio" Version="2.2.0" />
  </ItemGroup>
</Project>

我从Resharper的测试运行程序得到了一个非决定性的测试结果，而测试浏览器没有显示任何测试。为了进一步分解它，我使用以下命令（作为管理员）运行它：

我尝试了以下简单的方法：

• 重新启动VS
• 重新启动我的机器
• 创建NUnit测试，MSTests
• 以管理员身份运行一切
• 更新所有库
• 将库还原为教程中的旧版本
• 我的.NET4.6.1项目的测试正在成功运行，所以我认为它只是.NETCore
• 检查windows日志中是否存在异常

如有任何帮助或线索，将不胜感激

注意：我正在amazon工作区工作，因此它可能会以某种方式影响这一点，我还不知道。

尝试从以下位置更改SDK版本：

<PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.3.0-preview-20170628-02" />

致：

并将您的.net core更新到最新版本。

您好，谢谢您的回答，我尝试过，昨天甚至将其更新到15.5，但仍然失败。另外一点：这为我解决了问题（升级到更高版本而不是旧版本）。如果无法正常工作，您可能希望将此报告为错误。
