You have a common interface that is used by multiple concrete classes and you donít want to specify each Ninject binding manually.


The solution to this problem is very similar to my previous post on Automatic Ninject Bindings because it also leverages the NuGet package Ninject.extensions.conventions.

In this example, letís assume you have a single interface called IService<T>.† This interface contains a generic reference to a class or object (e.g. a database model).† Then you have multiple classes that implement the interface.† E.g. UserService : IService<User>.

With the following line of code, all of your classes that implement the IService interface will automatically bind to the corresponding class:

 ††††††††††† var kernel = new StandardKernel();

 ††††††††††† kernel.Bind(x =>

 ††††††††††† {

 †††† †††††††††††x.FromThisAssembly()

 ††††††††††††††††††† .SelectAllClasses()

 ††††††††††††††††††† .InheritedFrom(typeof(IService<>))

 ††††††††††† ††††††††.BindSingleInterface();

 ††††††††††† });
