What is Websharp Service Locator
For multi-tier application Systems, we usually divide them into clients, application services, and databases. At the application service level, we need to consider at least two issues:
• How to implement business logic
• How to provide services to clients.
We may use a variety of te

Until now, the examples you see are only looking for chapter headings that appear anywhere. Any occurrence of a string ' Chapter ' followed by a space and a number may be a true chapter title, or it may be a cross-reference to other chapters. Because true chapter headings always appear at the beginning of a line, you need to design a method to find only the headings instead of looking for cross-references.

Motivation
Service locator is a common mode during system development. The pattern can be found in the inversion of control containers and the dependency injection pattern written by Martin Fowler. Service locator defines the responsibility of generating, storing, and obtaining objects in the BLL layer, so that the system does not need to know how to generate and store objects when obtaining objects, effect

When a component needs to call multiple services, different services may initialize their instances in different ways. Developers have to understand the APIS initialized by all services so that they can be correctly used in programs.
The initialization process of some services consumes a lot of resources. Therefore, repeated service initialization will greatly increase the resource usage and performance consumption of the system. The program requ

There is a boom in the Java community that uses lightweight containers to help assemble components from different projects and integrate into a cohesive application.
These underlying containers have a common pattern of demonstrating how they assemble components, and they propose a concept called "control reversal" (Inversion of controls).
Next we delve into how the pattern works in "Dependency Injection" (Dependency injection) and compares it to the service
