提供商托管应用程序中的问题 [英] Issue in Provider Hosted App

问题描述

目前我们有提供商托管应用（MVC）。我们在构建项目时遇到了以下错误。该项目的目标是.Net 4.5框架工作

"The Csc"任务失败意外。

System.TypeLoadException：无法从程序集'mscorlib，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089'加载'System.ValueTuple`3'类型。

  在Microsoft.CodeAnalysis.BuildTasks.ManagedToolTask​​.GenerateCommandLineCommands（）

  在Microsoft.Build.Utilities.ToolTask​​.Execute（）

  在Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute（）

  在Microsoft.Build.BackEnd.TaskBuilder。< ExecuteInstantiatedTask> d__26.MoveNext（）"

我们尝试过以下选项，但仍未解决问题。

1. 使用Nuget manger更新System.ValueTuple 4.5.0到4.3.1
2. 使用Nuget卸载System.ValueTuple经理并删除了项目中的所有参考文献。
3. 我们删除了所有包并重建了解决方案

Hi,

Currently we have Provider hosted app(MVC). We have got below error while building the project. The project is targeted .Net 4.5 frame work

"The "Csc" task failed unexpectedly.

System.TypeLoadException: Could not load type 'System.ValueTuple`3' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

   at Microsoft.CodeAnalysis.BuildTasks.ManagedToolTask.GenerateCommandLineCommands()

   at Microsoft.Build.Utilities.ToolTask.Execute()

   at Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute()

   at Microsoft.Build.BackEnd.TaskBuilder.<ExecuteInstantiatedTask>d__26.MoveNext()"

We have tried below options but still issue not solved.

1. Update System.ValueTuple 4.5.0 to 4.3.1 using Nuget manger
2. Uninstall System.ValueTuple using Nuget manager and removed all references from the project.
3. We have removed all packages and rebuild the olution
