ServicePointManager.DefaultConnectionLimit in .net

问题:

I am porting a web api 2 service to .net core and I found this line in my old web api service.

ServicePointManager.DefaultConnectionLimit = int.MaxValue;

This line of code increases the connection limit. I don't know if it's for the computer or the framework or just the application. And after reading this answer on stackoverflow, I also realise that setting it to int.max may not be the best idea. However I would still like to have control over it in my new .net core service.

How do I modify/increase DefaultConnectionLimit in .net core. Also, How do I even know what's the default limit in .net core ? (if that's a valid question :) )

In ASP.NET 5 apps, use WinHttpHandler.MaxConnectionsPerServer. Its default value is int.MaxValue.

For details, see the .NET Portability Analyzer from the Visual Studio Gallery and WinHttpHandler.MaxConnectionsPerServer on MSDN.
