Question

所以我有一个使用Topshelf作为Windows服务运行的.NET 4.6.1应用程序，我还有一个ASP.NET核心Web应用程序（MVC和API），它当前作为服务运行并在使用Microsoft.AspNetCore.Hosting和Microsoft.AspNetCore.Hosting.WindowsServices创建自己的流程。我想要实现的是，我可以从.NET应用程序中启动AspNetCore Hosting，所以我只有一个进程。

然而，当我尝试使用此代码时：

bool isService = true;
if(Debugger.IsAttached || args.Contains("--console"))
{
    isService = false;
}

var pathToContentRoot = Directory.GetCurrentDirectory();
if(isService)
{
    var pathToExe = Process.GetCurrentProcess().MainModule.FileName;
    pathToContentRoot = Path.GetDirectoryName(pathToExe);
}

var host = new WebHostBuilder()
.UseKestrel()
.UseContentRoot(pathToContentRoot)
.UseIISIntegration()
.UseStartup<Startup>()
.UseApplicationInsights()
.Build();

host.Run();

我遇到了很多错误。起初我认为这是因为使用了不同的目标.net平台，但即使将两者调整为4.6.1并将asp.net核心数据更新为最新版本，它仍会输出这些错误（这就像1 / 30个原始错误长度）：

更新：

因此，对于每个尝试做我所做的事情的人来说，通过在控制台项目中托管Web项目（都针对.NET FW 4.6.1）。看起来这不起作用的原因是在编译时，当ASP尝试使用razor渲染页面时，它无法以正确的方式解析命名空间，因此找不到合适的DLL来使用。另一种方式很好。通过简单地运行aspnet核心项目的其他功能，使用控制台和自托管。

也许尝试在web.config中添加netstandard引用，如下所示：

<system.web> 
<compilation debug="true" targetFramework="4.7.1" > <assemblies> <add `assembly="netstandard, Version=2.0.0.0, Culture=neutral,` PublicKeyToken=cc7b13ffcd2ddd51"/> </assemblies> </compilation> <httpRuntime targetFramework="4.7.1" />

从.NET Framework应用程序启动AspNetCore托管
