Azure Function .NET Framework 4.7.2 无法加载 System.Threading.Tasks.Extensions 4.2.0.0

我有一个包含 Azure Function 项目和类库的解决方案。当我尝试在函数项目中使用类库时，出现错误

Unable to load System.Threading.Tasks.Extensions 4.2.0.0

两个项目都安装了 System.Threading.Tasks.Extensions 4.5.4 NuGet 包。在这里我发现了一个重定向程序集版本的方法。这是类库项目的 xxx.csproj 文件

<Reference Include="System.Threading.Tasks.Extensions, Version=4.2.0.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51, processorArchitecture=MSIL">
  <HintPath>..\packages\System.Threading.Tasks.Extensions.4.5.4\lib\net461\System.Threading.Tasks.Extensions.dll</HintPath>
</Reference>

这是功能项目的 xxxx.csproj (System.Threading.Tasks.Extensions 4.5.4)

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net472</TargetFramework>
    <AzureFunctionsVersion>v1</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Azure.Messaging.ServiceBus" Version="7.6.0" />
    <PackageReference Include="AzureFunctions.Autofac" Version="2.0.0" />
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions" Version="2.2.0" />
    <PackageReference Include="Microsoft.Azure.WebJobs.ServiceBus" Version="2.2.0" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="3.0.1" />
    <PackageReference Include="System.Threading.Tasks.Extensions" Version="4.5.4" />
  </ItemGroup>
  ...
</Project>

如何解决功能项目中的问题？

原文

I have a solution containing a Azure Function project and a class library.
When I try to use the class library in a function project I get an error

Unable to load System.Threading.Tasks.Extensions 4.2.0.0

Both projects have the System.Threading.Tasks.Extensions 4.5.4 NuGet package installed.
Here I found a way to redirect assembly versions. Here is xxx.csproj file of class library project

<Reference Include="System.Threading.Tasks.Extensions, Version=4.2.0.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51, processorArchitecture=MSIL">
  <HintPath>..\packages\System.Threading.Tasks.Extensions.4.5.4\lib\net461\System.Threading.Tasks.Extensions.dll</HintPath>
</Reference>

Here is xxxx.csproj of function project (System.Threading.Tasks.Extensions 4.5.4)

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net472</TargetFramework>
    <AzureFunctionsVersion>v1</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Azure.Messaging.ServiceBus" Version="7.6.0" />
    <PackageReference Include="AzureFunctions.Autofac" Version="2.0.0" />
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions" Version="2.2.0" />
    <PackageReference Include="Microsoft.Azure.WebJobs.ServiceBus" Version="2.2.0" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="3.0.1" />
    <PackageReference Include="System.Threading.Tasks.Extensions" Version="4.5.4" />
  </ItemGroup>
  ...
</Project>

我已尝试通过您的设置重现该问题。
能够构建应用程序，包引用中不会出现任何错误，但未正确加载 System.Threading.Tasks.Extensions

已替换，

<Reference Include="System.Threading.Tasks.Extensions, Version=4.2.0.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51, processorArchitecture=MSIL">
  <HintPath>..\packages\System.Threading.Tasks.Extensions.4.5.4\lib\net461\System.Threading.Tasks.Extensions.dll</HintPath>
</Reference>

与

  <Reference Include="System.Threading.Tasks.Extensions, Version=4.2.0.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51, processorArchitecture=MSIL">
      <HintPath>..\packages\System.Threading.Tasks.Extensions.4.5.4\lib\net461\System.Threading.Tasks.Extensions.dll</HintPath>
   </Reference>

I have tried to repro the issue with your settings.
Able to build the application without any errors in the package references, but assembly reference is not loaded correctly for System.Threading.Tasks.Extensions

Replaced,

<Reference Include="System.Threading.Tasks.Extensions, Version=4.2.0.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51, processorArchitecture=MSIL">
  <HintPath>..\packages\System.Threading.Tasks.Extensions.4.5.4\lib\net461\System.Threading.Tasks.Extensions.dll</HintPath>
</Reference>

with

  <Reference Include="System.Threading.Tasks.Extensions, Version=4.2.0.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51, processorArchitecture=MSIL">
      <HintPath>..\packages\System.Threading.Tasks.Extensions.4.5.4\lib\net461\System.Threading.Tasks.Extensions.dll</HintPath>
