.NET Core Configuration - System.Net connectionManagement/maxconnections?

Question

I am migrating a console app (REST client app) from .NET framework to .NET Core.

In my current (framework) version, I use the app.config file to set the System.Net configuration:

<system.net>
    <connectionManagement>
      <add address="*" maxconnection="65535"/>
    </connectionManagement>
</system.net>

In .NET Core, I have to use a JSON file for configuration. There is no documentation for implementing these settings using the new configuration schema. Does anyone know how this might look inside the new JSON config, or the correct way to implement this in Core? Do I need to build a designated "System.Net.json" config file (separate from an AppSettings.json) specifically to do this?

Thanks.

Assuming you are using Kestrel as your web server (and not doing it through IIS implementation), you should be able to set this in your UseKestrel in your BuildWebHost.

It would go something like this:

.UseKestrel(options =>
{
    options.Limits.MaxConcurrentConnections = 100;
})

You can also add this in your HttpClientHandler, It's called MaxConnectionsPerServer. It can be seen here.
