我安装了 .net core 2.2.0，我正在尝试从我使用 Visual Studio 2017 发布的同一台 PC 的部署文件夹运行我的 asp.net core mvc 应用程序的发布版本。
当我去运行它时，项目启动并按预期在我的 443 端口上启动网络服务器，但是当我访问服务器时，Kestrel 吐出一条错误消息:
fail: Microsoft.AspNetCore.Server.Kestrel[13]
Connection id "0HLLBBV3878EF", Request id "0HLLBBV3878EF:00000003": An unhandled exception was thrown by the application.

我的 dotnet 绑定(bind)是否存在问题，即发布未生成某些内容，或者我的观点之一访问了不在 .net 核心或其他内容中的内容？
请您参考如下方法:
有同样的错误，对我来说它有助于添加 <MvcRazorExcludeRefAssembliesFromPublish>false</MvcRazorExcludeRefAssembliesFromPublish>在.csproj文件。使用任何文本编辑器对其进行简单编辑，或在 VS 中右键单击您的项目，然后编辑项目文件。在第一个 <PropertyGroup> 中插入属性像这样:
<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
<TargetFramework>netcoreapp2.1</TargetFramework>
<GeneratePackageOnBuild>false</GeneratePackageOnBuild>
<!-- Fix for "System.InvalidOperationException: Cannot find compilation library location for package 'Microsoft.AspNet.WebApi.Client'" -->
<MvcRazorExcludeRefAssembliesFromPublish>false</MvcRazorExcludeRefAssembliesFromPublish>
</PropertyGroup>
<!-- ... -->
<Project>
然后重新发布。就我而言，问题也只发生在发布时，而不是在 VS 中调试期间。因此，在默认配置中，Razor 的引用似乎没有与其他 Razor 库一起发布。
我使用的是 ASP.NET Core 2.1，但它在 2.2 版上也可能对您有所帮助。
