How to prevent Rider from auto opening ASP.NET Core WebApp in browser after every run?

I am creating WebApp in Rider and I always have one (or more) window in browser opened with my App. And then when I make some change and rerun Application, Rider opens another tab in browser.

I hope it can be disabled. I looked for answer but couldn't find anything.

Every solution I found was about Visual Studio, but I couldn't find similar one in Rider.

Solution

You can turn it off in Properties\launchSettings.json, e.g.:

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:46186",
      "sslPort": 44347
    }
  },
  "profiles": {
    "ASP.NETCoreWebApplication1": {
      "commandName": "Project",
      "launchBrowser": false, <---- THIS
      "applicationUrl": "https://localhost:7104;http://localhost:5171",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development",
        "ASPNETCORE_HOSTINGSTARTUPASSEMBLIES": "Microsoft.AspNetCore.SpaProxy"
      }
    },
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": false, <--- THIS
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development",
        "ASPNETCORE_HOSTINGSTARTUPASSEMBLIES": "Microsoft.AspNetCore.SpaProxy"
      }
    }
  }
}

You can then confirm this change in Run->Edit Configuration...:
