我正在构建一个正在构建的.NET Core解决方案，但是当我尝试发布它时，会出现以下错误：
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.

在更高的详细程度上，我得到以下信息（我不知道这是否明显更好）：

有人可以告诉我这是什么，以及如何阻止它爆炸？这刚刚开始发生，我不知道为什么我甚至需要代码分析库来发布。
这种情况发生在Windows和Linux上，带有最新的.NET核心库（当时我写的是2.0.5）。
答案 0 :(得分：3)
好的，这很愚蠢，但确实有效。
我开始用谷歌搜索我能找到的所有关键字，然后在microsoft.aspnetcore.mvc.razor.viewcompilation上查找github问题。这最终导致我进入了Razor view compilation and precompilation in ASP.NET Core页面，而这个页面又发出了一个小小的警告：
重要
执行a时，Razor视图预编译当前不可用 ASP.NET Core 2.0中的自包含部署（SCD）。该功能将 2.1发布时可用于SCD。
现在，除了它不起作用之外，它本身并没有告诉你任何事情，但是跟进，它有点建议添加这样的一行：
<MvcRazorCompileOnPublish>false</MvcRazorCompileOnPublish>
...进入我的.csproj文件。
你认为这有用吗？我认为这完全失败了，因为MS会以这种神秘的方式爆炸而没有关于这个错误意味着什么的任何文档，但基本上，默认情况下，当你发布时，你预先编译你的剃刀视图，但是这个.NET Core 2.0从命令行或从linux开始基本上都不受支持......他们希望它能在2.1版本之间运行，但是......好吧，我们只是说我赢了屏住呼吸。
希望这可以帮助别人撞墙，寻找答案。
