Set up building Web Services for Asp.net applications

1. What is application settings?
Application settings usually refer to a series of parameters closely related to the application. In Windows applications based on forms, application settings mainly include parameters such as location and size that affect the application layout, and parameters such as color and shape that affect the application appearance. In addition, it also includes application language, culture, and other settings as well as data sources and connection strings. These parameter settings are widely used in program development, and some are used to maintain the consistency and continuity of the application, such as saving the form size, position, and background color at the end of the application, these settings are restored when the application is executed next time. Other parameters make the program code more concise and efficient, such as saving the database connection string for multiple calls.
Unlike windows applications based on forms, web-based Asp.net applications have their own particularity and are network-oriented. This determines that the asp.net application settings include not only the above parameters, but also,
# Identity authentication, authorization, and other security mechanisms
# Network transmission protocol type and http handler for specific types of documents
# Transaction Processing
# Set timeout for all pages
# Customize the error page to replace the default IIS error page
# Session and session status information
# Page cache behavior
# Customization and Expansion
It can be seen that the parameter types set by the asp.net application are more abundant. In actual development, they are not only used to improve application security and efficiency, but also easy to manage and customize requirements for specific users.
Ii. Why do we need to set the asp.net application as a web Service externally?
There is no need to mention the advantages of web Services. The overwhelming publicity and wide application of the media in many fields have been enough to explain the problem. However, it should be emphasized that the web Service is actually an asp.net application, but it is re-organized. Specifically, web Services provide the implementation of shared objects between different applications. Through simple reference, you can access the functions implemented by another program in the program, not just the functions implemented by asp.net in the browser. Obviously, web services also have many features and features of General asp.net applications. Asp.net and web services both have the state management function, which is a typical example.
