.net-core-2.0 azure应用程序服务502.5错误 [英] .net-core-2.0 azure app service 502.5 error

问题描述

在CI部署到天蓝色的应用程序服务后收到502.5错误。

Getting a 502.5 error after CI deployment to azure app service.

运行 dotnet {myproject} .dll 在调试控制台上，这是我得到的错误：

When running dotnet {myproject}.dll on the debug console this is the error I get:

未处理的异常：System.IO.FileLoadException：无法加载文件或程序集' System.Diagnostics.DiagnosticSource，版本= 4.0.2.1，区域性=中性，PublicKeyToken = CC7b13ffcd2ddd51'。找到的程序集的清单定义与程序集引用不匹配。 （来自HRESULT的异常：0x80131040）Microsoft.AspNetCore.Hosting.WebHostBuilder.BuildCommonServices（AggregateException& amp; HostingStartupErrors）中的

运行 dotnet --version 返回 2.0.0

还有其他人遇到这个问题，以及有关如何解决的任何建议吗？

Anyone else run into this yet and any suggestions on how to resolve?

推荐答案

发现了问题。让我首先添加更多信息。这最初是一个.net-core-1.1项目，我按照Microsoft提供的说明将其更新为2.0。升级后，我在本地运行完全没有问题，但是一旦尝试发布我的azure应用程序服务，我就不断收到IIS错误。最后的努力是今天早上从头开始创建一个新的.net-core-2.0项目，并注意到新项目文件包含以下内容：

Found the issue. Let me start by adding a little more information. This was originally a .net-core-1.1 project that I updated to 2.0 following instructions provided by Microsoft. After upgrading, I had no issues at all running locally, but once I tried to publish my azure app service, i kept getting the IIS error. Last ditch effort was to create a new .net-core-2.0 project from scratch this morning and noticed that the new project file contained this:

  <ItemGroup>
    <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.0" />
  </ItemGroup>

我将其添加到现有项目文件（从1.1升级的文件）中，现在错误消失了并解决了问题。

I added that to my existing project file (the one upgraded from 1.1) and now the error is gone and issue resolved.
