Question

我在项目中遇到问题，引用了2个软件包，然后引用了Newtonsoft.Json但两个版本都不同。我正在使用Refit和Microsoft.NET.Sdk.Functions的nuget包。当我尝试构建解决方案时，我收到以下错误：

C:\dev\noddy\noddy-api\src\noddy.Api>dotnet build
C:\dev\noddy\noddy-api\src\noddy.Api\noddy.Api.csproj : error NU1607: Version conflict detected for Newtonsoft.Json. Reference the package directly from the project to resolve this issue. \r
C:\dev\noddy\noddy-api\src\noddy.Api\noddy.Api.csproj : error NU1607:  noddy.Api (>= 1.0.0) -> Refit (>= 4.0.1) -> Newtonsoft.Json (>= 10.0.3) \r
C:\dev\noddy\noddy-api\src\noddy.Api\noddy.Api.csproj : error NU1607:  noddy.Api (>= 1.0.0) -> Microsoft.NET.Sdk.Functions (>= 1.0.2) -> Newtonsoft.Json (>= 9.0.1).

现在，如果我按照它说的做，并直接从我的项目中引用包，那么在构建时会出现另一个错误：

我尝试添加程序集重定向但似乎忽略了这些。

我还尝试删除所有软件包并将它们逐个添加回来，但仍然没有任何乐趣：

有人对如何解决这个问题有任何想法吗？

Answer 1

不幸的是，这是a known bug项目的Azure Functions MSBuild。所有发行版本都对Json.NET 9.0.1具有硬编码依赖性。报告的唯一解决方法是降级到1.0.0-alpha6版本。

缺少软件包摘要和描述，以及Github project中缺少文档，这清楚地表明这是一项正在进行的工作。

假设你做需要它，你可以尝试克隆.csproj中的仓库change the dependency并重建包。

与此同时，您应该向issue添加评论，并解释您也会受到影响。

要解决此问题，Line 39 of csproj应更改为：

<PackageReference Include="Newtonsoft.Json" Version="[9.0.1]" />

到

<PackageReference Include="Newtonsoft.Json" Version="9.0.1" />

对Microsoft.Azure.WebJobs个套件的测试版

还存在其他确切的版本依赖关系

2018年11月更新

repo的自述文件已更新on March 31 2018，其中包含解释为何锁定Json.NET版本以及如何处理此问题的常见问题解答：

问：我需要一个不同的Newtonsoft.Json版本。我该怎么办？

答：将您需要的版本添加到csproj中。例如，使用11.0.2将其添加到csproj

<PackageReference Include="Newtonsoft.Json" Version="11.0.2" />

问：为什么Newtonsoft.Json首先被锁定？

答：Newtonsoft.Json的版本被锁定以匹配函数运行时使用的版本

对（现已锁定）问题进行了长时间的讨论，该问题解释了解锁版本只会在部署之前延迟问题

Answer 2

遇到相关问题，无法安装Mirosoft.NET.Sdk软件包。通过使用vs2017创建新的Cloud-Azure功能项目来解决这个问题。该项目附带Mirosoft.NET.Sdk软件包版本1.0.6。将其更新到1.0.7实际上有效。然后安装牛顿9.0.1。从那以后，没有问题。

Answer 3

通过使用具有.net核心的Azure Functions v2，我能够使我的项目与Netwonsoft.Json 11.0.2一起工作：

  <PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
  </PropertyGroup>

Answer 4

在Azure中，函数运行时会加载特定版本的牛顿软件（当前在v2中为11.0.1，在v1中为9.0.1）.Json 之前通过队列绑定加载函数库

如果您使用与[11.0.1]二进制不兼容的任何函数（例如，v12中使用的任何新属性），则用于使其编译的任何变通办法都将导致诊断运行时失败。

由Microsoft.NET.Sdk.Functions引起的版本冲突
