"CheckFileSystemCaseSensitive"任务意外失败,无法加载文件或程序集'System.IO.FileSystem

Question

在我的Visual Studio 2017,ASP.NET Core,MVC web项目中,我刚刚添加了Microsoft.TypeScript.MSBuild NuGet包v2.3.1,同时将我的ASP.NET核心程序集从1.0.*更新到1.1.1.现在,当我构建项目时突然出现以下异常:

Severity    Code    Description Project File    Line    Suppression State
Error   MSB4018 The "CheckFileSystemCaseSensitive" task failed unexpectedly.
System.IO.FileNotFoundException: Could not load file or assembly 'System.IO.FileSystem, Version=4.0.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
File name: 'System.IO.FileSystem, Version=4.0.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'
   at TypeScript.Tasks.CheckFileSystemCaseSensitive.Execute()
   at Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute()
   at Microsoft.Build.BackEnd.TaskBuilder.<ExecuteInstantiatedTask>d__26.MoveNext()

双击异常消息将获取文件Microsoft.TypeScript.targets中的这些行:

<Target Name="CheckFileSystemCaseSensitive">
    <CheckFileSystemCaseSensitive
       MSBuildThisFileFullPath="$(MSBuildThisFileFullPath)" >
      <Output TaskParameter="IsFileSystemCaseSensitive"  PropertyName="IsFileSystemCaseSensitive" />
    </CheckFileSystemCaseSensitive>
</Target>

它说"MSBuildThisFileFullPath未定义".

我已经尝试添加引用NETStandard.Library,如下所示:https: //github.com/dotnet/corefx/issues/16206,但这没有任何区别.

诊断MSBuild输出如下所示:

1>Target "CheckFileSystemCaseSensitive" in file "C:\Users\dkent\.nuget\packages\microsoft.typescript.msbuild\2.3.1\tools\netstandard1.3\Microsoft.TypeScript.targets":

谢谢你的任何建议.

我在Vs2015中遇到了同样的错误，我从https://www.microsoft.com/en-us/download/confirmation.aspx?id=48593安装了type script ，并且错误消失了，你可以尝试一下
