C#4.0 HTTP协议无法使用TLS1.2的问题

在发送HTTP请求前加入下行代码 ServicePointManager.SecurityProtocol = (SecurityProtocolType)192 | (SecurityProtocolType)768 | (SecurityProtocolType)3072; 如果是4.5以上版本可以直接使用 ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityP

C# .net 提升 asp.net mvc, asp.net core mvc 并发量

1.提升System.Net.ServicePointManager.DefaultConnectionLimit 2.提升最小工作线程数 使用ThreadPool.GetMinThreads(out workerThreads, out completePortsThreads); 方法可以得到当前“最小工作线程数”和“最小IO工作线程数”，这两个值默认等于CPU核心数，我这里等于6. 显然，这点
