无法调试Azure函数 - Visual Studio 2017

Question

我使用 Azure Functions 工具和 Azure Functions V1 创建了一个全新的项目：

我按下F5，出现黄色闪电图标，然后出现错误信息：

"在特定注册的激活期间出现错误。请参阅内部异常以获取详细信息。 注册: Activator = WebScriptHostManager(DelegateActivator), Services =[Microsoft. Azure.WebJobs.Script.WebHost.WebScriptHostManager], Lifetime = Autofac.Core.Lifetime.CurrentScopeLifetime, Sharing = None, Ownership = ExternallyOwned ---> “Microsoft.Azure.WebJobs.Script.Utility”类型的初始化程序引发了一个异常。(有关详细信息，请参见内部异常。)"

我的设置如下：

Visual Studio 2017 - 15.6.7

Azure SDK Functinons 1.0.12

Azure Function V1

Azure Web Job Tools - 15.0.40215.0

Azure CLI 1.0.12

这是我在VS控制台中的输出：

我已经尝试过： 卸载并重新安装Azure Dev工作负载和CLI工具 我还没有尝试卸载/重新安装VS，因为这至少需要半天时间。

我怀疑问题出在Azure CLI上。

我对Azure Functions + VS感到非常沮丧。 要让这个东西正常工作简直是一场噩梦！

你确定你的 Azure Web Job Tools 版本是 15.0.402015.0 而不是 15.0.40215.0 吗？ - Joy Wang

我认为这是可能的。有什么未被勾选的吗？ - Joy Wang

除了 PowerShell，我已经检查了一切。问题仍然存在。 - Stanza

看起来你的问题出现在本地 Functions Host 运行时中。请尝试查找更多错误详细信息。尝试搜索默认日志位置 <DefaultTempDirectory>\LogFiles\Application\Functions 和 Windows 事件日志。 - Vladislav

我无法重现你的问题，由于 CLI 没有显示内部异常，很难确定问题的原因。我已在我们的存储库中提交了一个问题（https://github.com/Azure/azure-functions-core-tools/issues/456），一旦进行更改，就应该能够找到并解决问题，如果问题再次出现。否则，恐怕我没有比你已经收到的建议更多的建议：确保你正在使用最新版本的工具。 - Katy Shimizu

Answer 1

问题已解决！

多亏了Jerry Liu，我成功调试了Azure Function Core Tools的源代码。

错误信息是与Newtonsoft相关的：

"Could not load type 'Newtonsoft.Json.Converters.ExpandoObjectConverter' from assembly 'Newtonsoft.Json, Version=9.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'."

我刚刚运行了nuget来更新Newtonsoft的最新版本的源代码。

然后我将重新构建的源代码复制到：

C:\Users[MyUserName]\AppData\Local\AzureFunctionsTools\Releases\1.0.12.1\cli

现在它可以正常工作了。

感谢所有帮助我解决问题的人！

很高兴你解决了它！只是出于好奇，现在你能直接在VS中运行源代码，而不需要将编译文件复制到cli文件夹中吗？ - Jerry Liu

嗨，Jerry，是的，我无法弄清楚如何使我的Azure函数代码指向经过修改的Azure核心工具的源代码，因此我手动将我的函数文件复制到源代码目录中。一定有办法... - Stanza

是的，目前它指向那个路径，但我想让我的函数指向修改后的Azure Core工具源代码。我找不到怎样做，所以最后我只是将我的函数项目文件复制到了Azure Core工具源代码目录中。 - Stanza

我刚从git的源代码https://github.com/Azure/azure-functions-core-tools/tree/v1.x下载了它，然后运行nuget获取最新的Newtonsoft包并重新构建了解决方案。但我没有将我的函数项目更新为最新的Newtonsoft。 - Stanza

非常抱歉回复晚了。新版本似乎运行良好，不需要使用修改后的核心工具。顺便提一下，在发布项目到 Azure 时修改核心工具源代码可能会带来意想不到的风险，因为函数核心工具无法在线更改。此外，如果您想使用 cli 而不是 VS 中使用的 cli，请参阅此答案。 - Jerry Liu

Answer 2

我曾经遇到了同样的错误，并追踪到 Newtonsoft.Json.dll 版本不一致。通过从 GAC 卸载版本为 10.0 的 Newtonsoft.Json 来解决此问题（Azure Functions 需要 9.0 版本）。

因此，在 Visual Studio 命令提示符中运行 gacutil /l | findstr Newtonsoft，然后在找到的每个高于 9.0 版本的 DLL 上运行 gacutil /u。

如果这样做不起作用，建议从源代码运行 Azure Functions 工具 (func.exe)。从 https://github.com/Azure/azure-functions-core-tools/ 克隆它，检出 v1.x 分支，并使用 host start --pause-on-error 作为命令行参数以及您的 Azure 函数的输出文件夹作为工作目录来运行 Azure.Functions.Cli 项目。如果在调试器中设置了所有 CLR 异常的断点，则应该能够很快地跟踪到问题。

感谢您的见解，Joe。我已经确定我的 Newtonsoft 是正确的 - Newtonsoft.Json，版本=9.0.0.0，文化=中性，公钥令牌=30ad4fe6b2a6aeed，处理器架构=MSIL。 - Stanza

我已经下载了CLI项目，但不确定如何将我的函数指向源代码，以及要执行的命令是什么。抱歉，之前没有做过这些东西。。 - Stanza

Answer 3

在v2上对我有效，而不是v1。我必须进入.csproj文件并将AzureFunctionsVersion添加到PropertyGroup中。

<PropertyGroup>
  <TargetFramework>net461</TargetFramework>
  <AzureFunctionsVersion>v2</AzureFunctionsVersion>
</PropertyGroup>
