All windows developers are familiar with the "DLL hell" version control problem. As a new applicationProgramIf the installed component overwrites the component of the old application, DLL hell may occur. It can cause abnormal behavior of old applications, or completely "strike ". Currently, the. NET Framework architecture completely isolates reference program components, which are used by applications to load those components that were originally generated and used for lateral view. If an applic
