C# 有没有办法将owin startup.cs配置为在全局asax应用程序启动之前运行?
我试图在MVC5中实现每个请求的容器和每个请求的事务模式。我已经利用全球asax为其编写了大部分代码。但是我在创建多个上下文时遇到了问题,因为owin正在创建新的DbContext类,作为其startup.cs的一部分。是否有任何方法可以在全局asax应用程序启动事件之前运行owin,以便检索在那里创建的现有上下文?我不熟悉这些模式,所以如果这个问题听起来不对,我愿意接受其他建议C# 有没有办法将owin startup.cs配置为在全局asax应用程序启动之前运行?,c#,asp.net-mvc-5,owin,C#,Asp.net Mvc 5,Owin,我试图在MVC5中实现每个请求的容器和每个请求的事务模式。我已经利用全球asax为其编写了大部分代码。但是我在创建多个上下文时遇到了问题,因为owin正在创建新的DbContext类,作为其startup.cs的一部分。是否有任何方法可以在全局asax应用程序启动事件之前运行owin,以便检索在那里创建的现有上下文?我不熟悉这些模式,所以如果这个问题听起来不对,我愿意接受其他建议 public IContainer Container { get { return
