我有.net标准2.0库（sdk = Microsoft.NET.Sdk.Razor），称为SelfHost。 SelfHost使用MVC启动Kestrel Web主机服务器。 SelfHost还包含控制器和视图。构建生成SelfHost.Views.dll，从SelfHost加载控制器，一切正常。棘手的部分是：我希望SlefHost还可以从客户端应用程序（引用此库的程序集）中加载控制器和视图。 SelfHost使用以下命令从另一个程序集中检测控制器：
services.AddApplicationPart(clientAssembly)
从另一个程序集中检测视图是通过以下方式实现的：
services.Configure<RazorViewEngineOptions>(options => options.FileProviders.Add(new EmbeddedFileProvider(clientAssembly));
在这种方法中，视图构建动作必须设置为“嵌入式资源”
案例1：
运行使用SelfHost的.net核心控制台应用程序（sdk = Microsoft.NET.Sdk），而无需向控制台应用程序添加其他控制器和视图。因此，我们拥有仅带有SelfHost控制器和视图的干净控制台应用程序。
结果1 ： 一切正常。我有权访问控制器，并返回视图。
案例2： 运行使用SelfHost的.net核心控制台应用程序（sdk = Microsoft.NET.Sdk。 Razor ），配合向控制台应用程序添加其他控制器和视图。因此，我们拥有控制台应用程序，其中包含来自自托管主机的控制器/视图和来自控制台应用程序的控制器/视图。
结果2 一切正常。我可以访问SelfHost和控制台应用程序控制器。从SelfHost和控制台应用程序返回的视图。
情况3： 运行使用SelfHost的.net核心控制台应用程序（sdk = Microsoft.NET.Sdk，不带Razor），使用向控制台应用程序添加其他控制器和视图。因此，我们拥有控制台应用程序，其中包含来自自托管主机的控制器/视图和来自控制台应用程序的控制器/视图。
结果3：
当尝试从控制台应用程序访问视图时，我得到：

当控制台应用程序位于.net框架堆栈上时，也会发生此错误。 我想这是因为没有可用的razor sdk来编译此视图。 有什么解决办法吗？我想在.net框架组件中也使用此SelfHost库，在该组件中我无法将sdk设置为Microsoft.NET.Sdk.Razor。
