.net core System.Runtime 4.2.1.0 building v2 Azure Functions项目的FileNotFoundException

我尝试构建Azure Functions v2项目时出错。奇怪的是，这种情况并不总是发生。我尝试了Visual Studio 2017（15.9.3）和Visual Studio 2019（预览版1.1）的各种组合，以及在托管的2017代理上构建Azure DevOps，同时在1.0.22、1.0.23和1.0.24之间更改SDK的功能

• 在版本为1.0.24的Azure DevOps上，它总是会因此错误而失败
• 它总是在VS2019版本1.0.24中成功
• 与2017年和2019年相比，v1.0.22总是失败
• 其他的组合无论失败与否都是命中或未命中的

这似乎有点像这个问题，没有得到答案：

以下是错误：

System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime, Version=4.2.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

这是我的.csproj文件：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
    <AssemblyName>MyProject.FunctionsCore</AssemblyName>

  <ItemGroup>

我解决了相同的错误，但在中（它发生在VisualStudio中生成T4模板时）

尝试将此bindingRedirect放入

C:\Users\\AppData\Local\Microsoft\VisualStudio\15.0\u 29f8d23a\devenv.exe.config中
->
所有其他bindingRedirect的位置在哪里


在MSDN论坛[1]中通过同样的方法解决这个问题：我在这里创建了一个关于同一问题的问题：自从你发布了你的问题后，你找到解决方案了吗？奇怪的是，你的答案还没有人喜欢。在组合.Net Framework和.Net核心3.0项目时，您也会遇到此问题
