kestrel-http-server

I'm writing a simple ASP.NET Core service using ASP.NET Core empty ( web ) template. By default, it binds to port 5000 but I would like it to bind to a random available port on the system. I can do so by modifying BuildWebHost to: public static IWebHost BuildWebHost(string[] args) => WebHost.CreateDefaultBuilder(args) .UseStartup<Startup>() .UseUrls("http://*:0") // This enables binding to random port .Build(); It binds to a random port but how do I determine from within the application which port I'm listening to? Hosting addresses of ASP.NET Core application could be accessed via

When deploying a new version of an existing .net core website. How do I first safely stop the old running kestrel app? Here is an exmaple of what I would like to write (Pseudo deployment script): dotnet stop mysite/mysite.dll <---- this line here mv mysite/ mysite.bak/ cp newly-published-mysite/ mysite/ dotnet run mysite/mysite.dll killall dotnet seems a little unsafe. How would it work if I were hosting two small sites on one box? Ilya Chumakov Accordingly to this discussion , there is no safe way to stop Kestrel now. You need to find a PID by name of your dll and kill it : kill $(ps aux |

Background When hosting a (non-Core) ASP.net site on IIS 8+ it is possible to utilize the IIS Application Initialization Module to pro-actively initialize ('warm-up') a web application when IIS starts up (or, I believe, when an app pool is recycled). As far as I know, this is not possible when hosting a .net Core app on IIS. I have also noticed that when hosting a .net Core (1.1) app on IIS, the dotnet.exe process (Kestrel) is killed as part of an application pool recycle event. This process is then only restarted when the first new request is made. I'm asking the below questions because I am

I am bringing up command line and running my app using dotnet run command. This starts Kestrel and brings up my application. How should I go with identify to which process to attach debugger so I can debug the website that Kestrel now hosts? I specifically need to be able to do it this way - meaning I can't use standard F5. Unfortunately, there is no way to tell right now using the tools provided by Visual Studio or .NET Core. Notice, though, that the community has already requested for this feature here , so you can voice your opinion there. Currently, the best option is to follow the steps

I've got an ASP.NET Core 2.0 app which I intend to run as a stand-alone application. The app should start up and bind to an available port. To achieve this I configure the WebHostBuilder to listen on " http://127.0.0.1:0 " and to use the Kestrel server. Once the web host starts listening I want to save the url with the actual port in a file. I want to do this as early as possible, since another application will read the file to interact with my app. How can I determine the port the web host is listening on? You can achive it in Startup class in method Configure. You can get port from

I am trying to understand the entire web/framework/application stack when installing ASP.NET 5 on Linux. All the instructions I have read, including this one haven't really answered my question: Why can't Nginx server work without Kestrel like here: http://www.mono-project.com/docs/web/fastcgi/nginx/ ? Or am I way off. I'm trying to understand what the reason is for this structure: .NET Core(or mono) --> Kestrel --> Nginx Isn't Kestrel just another web server like Nginx but with a lot less features? ASP.NET Core (ASP.Net 5) doesn't require Kestrel ! You're right, Kestrel is just a simple HTTP

I am trying to remove the IIS Express profile from my .NET Core launch settings but every time i repoen the solution, Visual Studio adds it back in again. For example, in a new project my launch settings looks like this { "iisSettings": { "windowsAuthentication": false, "anonymousAuthentication": true, "iisExpress": { "applicationUrl": "http://localhost:55735/", "sslPort": 0 } }, "profiles": { "IIS Express": { "commandName": "IISExpress", "launchBrowser": true, "environmentVariables": { "ASPNETCORE_ENVIRONMENT": "Development" } }, "MyProject": { "commandName": "Project", "launchUrl": "http:/

I am trying to host an ASP.Net Core MVC application (https redirection is enabled) on Ubuntu server, using Nginx as a reverse proxy. I have created and installed a local SSL certificate using OpenSSL. When i run my application using dotnet CLI it listens on both http://localhost:5000 & https://localhost:5001 , and i am able to access it on web using https (http requests are being redirect to https by Nginx). The problem is when i try to run the as a service, it only listens on http://localhost:5000 . Here's the *.service file : [Unit] Description=Test ASP.Net core web application service.
