我们的ASP.NET核心RC1应用程序停止工作，然后又开始工作 [英] Our ASP.NET core RC1 application stopped working and then started working again

问题描述

我们已经在ASP.NET核心RC1(候选发布1)上构建了一个.NET应用程序，并将其部署在Windows Azure的Web App容器中.到8月2日，该应用程序停止了一整夜的工作.我们发现，这是由于Microsoft在该日期之前停止支持RC1(以及该问题的RC2)引起的.

We have built an .NET application on ASP.NET core RC1 (release candidate 1) and deployed it on Windows Azure in an Web App container. By August the 2'nd the application stopped working over night. We found out it was caused by the fact that Microsoft stopped supporting RC1 (and RC2 for that matter) by that date.

奇怪的是，到今天，该应用程序再次开始工作，而我们这边没有任何改变.

The strange thing is that by today the application started working again without any change from our side.

任何人都可以解释这种行为吗?对于容器环境中的此类更改，我感到不太满意.

Can anyone explain that behavior? I don't feel very comfortable with these kind of changes in the container environments.

NB:我应该补充一点，我们在日志文件中看到的错误是这样的:

NB: I should add that the error we saw in the log files was this one:

MissingMethodException: Method not found: 'Newtonsoft.Json.JsonSerializerSettings Microsoft.AspNet.Mvc.MvcJsonOptions.get_SerializerSettings()'

推荐答案

我可以解释发生了什么:Json.NET v6.0.4版本被错误地添加到GAC中.由于对Json.NET进行版本控制的方式，bin文件夹中具有不同6.x版本的应用程序最终将其加载到GAC中.您的RC1应用程序可能具有v6.0.7，并且由于v6.0.4缺少API而崩溃了.

I can explain what happened: a version of Json.NET v6.0.4 was mistakenly added to the GAC. Due to the way Json.NET is versioned, apps that had a different 6.x version in their bin folder ended up loading the one in the GAC. Your RC1 app probably has v6.0.7, and broke because v6.0.4 was missing APIs.

该程序集根本不应该存在于GAC中，因此，当我们意识到该问题时，便将其删除，这就是您的应用程序再次开始工作的时候.道歉停机.

This assembly is not supposed to be in the GAC at all, so when we realized the issue, we removed it, which is when your app started working again. Apologies for the downtime.

话虽如此，您真的应该离开不受官方支持的RC1.

That being said, you really should move away from RC1, which is not officially supported.
