dotnet core 方法“ValidateOptions”...没有实现

我正在构建一个 .NET Core 解决方案，该解决方案构建得很好，但是当我尝试发布它时，它崩溃并出现以下错误：

Method 'ValidateOptions' in type 'Microsoft.CodeAnalysis.CSharp.CSharpCompilationOptions' from assembly 'Microsoft.CodeAnalysis.CSharp, Version=2.3.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation.

     at System.Threading.Tasks.TaskReplicator.Replica`1.ExecuteAction(Boolean& yieldedBeforeCompletion)
     at System.Threading.Tasks.TaskReplicator.Replica.Execute()

在更详细的情况下，我得到以下信息（我不知道这是否明显更好）：

有人能告诉我这是什么，以及如何阻止它爆炸吗？这种情况最近才开始发生，我不知道为什么我什至需要代码分析库来进行发布。

这种情况发生在使用最新 .NET Core 库（我撰写本文时为 2.0.5）的 Windows 和 Linux 上。

好吧，这很愚蠢，但确实有效。

我开始用这个关键字搜索所有我能找到的东西，最后得到了在 github 上查找问题的线索microsoft.aspnetcore.mvc.razor.viewcompilation。这最终导致我ASP.NET Core 中的 Razor 视图编译和预编译 https://learn.microsoft.com/en-us/aspnet/core/mvc/views/view-compilation?tabs=aspnetcore2x页面，其中又包含这个漂亮的小警告：

重要的

执行操作时，Razor 视图预编译当前不可用 ASP.NET Core 2.0 中的独立部署 (SCD)。该功能将 2.1 版本发布时可用于 SCD。

现在，这本身并没有告诉你任何事情，除了它不起作用之外，但接下来，它建议添加这样一行：

<MvcRazorCompileOnPublish>false</MvcRazorCompileOnPublish>

...进入我的 .csproj 文件。

你相信这有效吗？我认为这对微软来说是完全失败的，因为它以如此神秘的方式爆炸，并且没有任何关于此错误含义的文档，但基本上，默认情况下，当您发布时，您会预编译您的剃刀视图，但这基本上不是在 .NET Core 2.0 中通过命令行或 Linux 支持...他们希望它能在 2.1 中工作，但是...好吧，我不会屏住呼吸。

希望这可以帮助其他人将头撞在墙上，寻找有关此问题的答案。
