ASP. NET Core Source Code Reading Notes (2), asp. netcore In the previous article, we mainly analyzed ASP. by default, NET Core depends on the storage and analysis of injection containers. This article mainly supplements some of the details ignored in the previous article: Service recycling, that is, service lifecycle. You can find the source code on GitHub. This

If the interface component is called again, the interface component is emptied and reused again.SingleInstance is a little different, that is, there is only one interface component in the new task, and Singletask is a number of other interface components in the new task.Use Singletask also note: If the interface component set the task Viscosity property, Android:taskaffinity property, then the interface component must not necessarily be the root component, if the specified task alrea

Abstract beanfactory--oriented interface is easier to expand beanfactory-interface is easier to expand. 2.

Abstract: This paper introduces the grammatical features of CG, special semantics and special operations supported, briefly introduces the approximate process of CG work, and focuses on how to encapsulate an object-oriented Cgshader class, which encapsulates the core function of CG, and uses this class to simplify the development work of CG. 1. CG syntax, semantics and special operationsIn the same way as C: CG has the syntax of Class C, there are man
