Vshost.exe.config is the configuration text when the program is run
Exe.config is the program that is copied to Vshost.exe.configapp.config after it is run is in Vshost.exe.config and exe.config no case is in effect, copied from app. config to exe.config and copied to VSHOST.E The xe.config write configuration file is written to the Exe.config file, and App. Config does not change. App. Config only reloads app.config,vshost.exe.config and exe.config in the development environment when Exe.config is lost, and the content is automatically created in the same way as App. Config. Vshost.exe.config and app. Config two files are not allowed, but the exe.config file is not limited. There are many articles on the web that speak of the app. config read-write method, but in fact the file program cannot change it.
