通过托管环境进行自我托管

Question

I'm trying to run ASP.NET Core (.NET 4.6.1) application as self hosting by means of weblistener

I've add a command:

"commands": {
    "web": "Microsoft.AspNet.Hosting --server Microsoft.AspNet.Server.WebListener --server.urls http://localhost:5000"
},

and necessary dependencies in project.json

When I start my application via Visual Studio it's works fine

src\ProjectName\bin\Release\net461\win7-x64\ProjectName.exe

ProjectName.exe starts as web server with Hosting environment: Development

When you start the application Visual Studio will automatically set the environment variables for you (based on settings from launchSettings.json in the properties folder).

When you run from commandline or double-click, you need to set the environment variable yourself using setx ASPNETCORE_ENVIRONMENT "Development" (Commandline) or $Env:ASPNETCORE_ENVIRONMENT = "Development" (Powershell).
