Dependency Injection in ASP.NET MVC 5 with StructureMap
Dependency Injection(DI) is a design pattern that let you write loosely coupled testable code. Typically your classes depend on other classes. Take a look at the following example. The above example shows the " HomeController " of an asp.net mvc application. Within the index method, you can see that it requires to create an instance of " Student " class to get the full name of a student. It is very clear that the Index method is tightly coupled with the Student class. This is a disadvantage when it comes to testing HomeController . Suppose that you have other methods, with similar types of class dependencies. So, each time when you test the code, you have to pass an actual instance Student class. This is tedious. You don't have the luxury of passing a fake student class to easily test your controllers. So how do we decouple the Student class from HomeController? This is where DI comes in handy. You can inject dependencies in several ways. Today i will sho
