C#/.NET/.NET Core的定时任务调度组件你用过那些呢，是Timer,FluentScheduler,TaskScheduler,Gofer.NET,Coravel,Quartz.NET还是Hangfire，又或者是其他的定时任务调度框架/组件呢？你常用的实现定时任务调度的方法又是怎样的呢？

1、C#代码 C#采用的RSACryptoServiceProvider类进行的加解密，由于该类默认是不支持私钥加密公钥解密的，需要通过BouncyCastle.Crypto.dll转换一下才可以。 代码如下：

<configuration>
<system .web>
<pages enableSessionState="false"></pages>

这样整个站点的页面默认是不打开Session的。
在你需要的页面的 使用如下 Page 设置
< %@ Page EnableSessionState="True"%>
或者在你需要打开Session的目录下，设置一个 web.config

2022年5月27日，刚刚把VS2019升级到了VS2022，安装时已经不提供.NET Framework 4.0和.NET Framework 4.5的目标框架了，打开VS也提示不支持目标框架。
View Details最近 C# 开发工具 Visual Studio 升级到了 2022，打开速度快了很多，开发体验也舒服很多。只是使用过程中遇到了一个比较尴尬的问题：默认Visual Studio 2022 不再支持安装 .NET Framework 4.5 组件，如下图所示：
选择组件里面已经不能选择4.5 / 4.0 的框架了。
背景 工作中遇到一个需求，客户要求按照他们指定的入参和出参开发一套WebService接口。 出入参不能有丝毫的出入，以方便他们的业务系统调用。 目标已明确，我们看看入参和出参(为了保护客户的商业机密，出入参都是虚构的)： 入参

出入参看上去都挺简单的，开工吧~ 项目创建 添加Web服务 项目框架 SoapUI获取的请求模板如图 去掉上一步的前缀 入参XML节点配置 出参根节点配置 出参列表节点名称配置 出参XML节点名称完整配置 最终效果：与客户要求入参出参完全一致 异常出参需要用HttpModule自定义输出 定义HttpModule 异常输出方法 异常测试，效果哪下图 忘了说，HttpModule要在web.config里注册一下 完整代码下载>>
