「CheckFileSystemCaseSensitive」任務意外失敗，無法加載文件或程序集'System.IO.FileSystem

Question

我的Visual Studio 2017，ASP.NET Core，MVC Web項目我只是添加了Microsoft.TypeScript.MSBuild NuGet包v2。 3.1，同時將我的ASP.NET Core程序集從1.0。*更新到1.1.1。現在，突然間，當我建立我的項目，我得到下面的異常：

上異常消息

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() 

雙擊需要一個在文件Microsoft.TypeScript.targets這些行：

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

地方說「MSBuildThisFileFullPath未定義」。

我試過添加引用NETStandard.Library，建議在這裏：https://github.com/dotnet/corefx/issues/16206，但這並沒有什麼區別。

診斷MSBuild的輸出是這樣的：

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

感謝您的任何建議。

我在Vs2015有同樣的錯誤，我從https://www.microsoft.com/en-us/download/confirmation.aspx?id=48593， 安裝類型的腳本和錯誤消失了，你可以給一個嘗試

Answer 2

（老問題，但是這可能會幫助其他人尋找一個解決這個問題）：

作爲爲VS項目配置TypeScript的替代方法，您可以嘗試將Microsoft TypeScript Compiler nuget包添加到解決方案而不是Microsoft.TypeScript.MSBuild包中。您可能需要配置<TypeScriptToolsVersion>在.csproj的文件（你只需要在主要和次要版本如）：

<TypeScriptToolsVersion>2.3</TypeScriptToolsVersion>
