Question

我使用最新的1.0.26 Microsoft.Net.Sdk.Functions NuGet程序包将Azure Function v2创建为DotNet Core库（2.1）。

我无法构建Azure功能，因为GenerateFunctions任务正在寻找System.Runtime的4.2.1.0版本。但是，没有该特定版本的NuGet软件包。

问题

谁正在寻找System.Runtime 4.2.1.0，我该如何解决？

这是构建的诊断日志部分，该部分失败：

如果我运行以下命令，则会得到完全相同的错误：

C：\ Users \ Chris.nuget \ packages \ microsoft.net.sdk.functions \ 1.0.26 \ tools \ net46> Microsoft.NET.Sdk.Functions.Generator.exe “ C：\ NoSuchCompany \ Service \ src \ bin \ Debug \ netcoreapp2.1 \ bin \ NoSuchCompany.Demo.Service.AzureFunctions.dll “” C：\ NoSuchCompany \ Service \ src \ bin \ Debug \ netcoreapp2.1 \“

我得到以下输出：

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.

我想知道为什么构建版本使用Microsoft.NET.Sdk.Functions.Generator的网络框架版本，因为有netcore版本。出于好奇，我尝试使用netcore版本：

C：\ Users \ Chris.nuget \ packages \ microsoft.net.sdk.functions \ 1.0.26 \ tools \ netcoreapp2.1> dotnet Microsoft.NET.Sdk.Functions.Generator.dll “ C：\ NoSuchCompany \ Service \ src \ bin \ Debug \ netcoreapp2.1 \ bin \ NoSuchCompany.Demo.Service.AzureFunctions.dll” “ C：\ NoSuchCompany \ Service \ src \ bin \ Debug \ netcoreapp2.1”

没有错误。我猜.net 4.6版本有问题。你呢？

Answer 1

我在Microsoft.NET.Sdk.Functions.Build.targets文件中找到了使用.Net Core运行时而不是.Net Framework的条件：

 <PropertyGroup>
      <UseNETCoreGenerator Condition="$(UseNETCoreGenerator)=='' AND ($(AzureFunctionsVersion) == 'v2' OR $(AzureFunctionsVersion) == 'v2-prerelease' )">true</UseNETCoreGenerator>
</PropertyGroup>

然后我查看了我的Azure Functions的.csproj文件，发现AzureFunctionsVersion标记拼写错误，并且在Function之后缺少s：

<PropertyGroup>
  <TargetFramework>netcoreapp2.1</TargetFramework>
  <AzureFunctionsVersion>v2</AzureFunctionsVersion>
  <AssemblyName>NoSuchCompany.Demo.Service.AzureFunctions</AssemblyName>
  <RootNamespace>NoSuchCompany.Demo.Service</RootNamespace>
  <OutputType>Library</OutputType>
</PropertyGroup>

一旦更正，我将获得预期的成功构建输出，尤其是指示使用.Net核心生成器的部分：

为什么GenerateFunctions在查找System.Runtime，Version = 4.2.1.0时失败，并抛出FileNotFoundException）？
