我在尝试构建 Azure Functions v2 项目时遇到错误。奇怪的是它并不总是发生。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 Hosted 2017 代理上构建 Azure DevOps,以及在 1.0.22 和 1.0 之间更改 Functions SDK。 23 和 1.0.24。
- 在 Azure DevOps v1.0.24 上总是失败并出现此错误。
- 它总是在 VS 2019 v1.0.24 上成功
- 在 VS 2017 和 2019 上使用 v1.0.22 总是失败
- 其他组合无论是否失败,都是碰运气。
好像有点类似这个问题,没得到答案: .NET Core and Azure Functions - build error System.Runtime 4.2.0.0
这是错误:
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.

FunctionsCore C:\Users\myusername\.nuget\packages\microsoft.net.sdk.functions\1.0.24\build\netstandard1.0\Microsoft.NET.Sdk.Functions.Build.targets 39
这是我的 .csproj 文件:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>netcoreapp2.1</TargetFramework>

最佳答案
我解决了同样的错误,但在 another context 中(在 Visual Studio 中生成 T4 模板时发生)。
尝试将此 bindingRedirect 放在 C:\Users\<user>\AppData\Local\Microsoft\VisualStudio\15.0_29f8d23a\devenv.exe.config
内的 <configuration>
内 -> <runtime>
-> <assemblyBinding>
其他所有 bindingRedirect 都在哪里
<dependentAssembly>
<assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="4.0.0.0"/>
</dependentAssembly>
