Convention based binding for Ninject

Ninject.Extensions.Conventions

Provides a configuration by convention extension for Ninject.

Sample uses

Binding default single interface

IKernel kernel = new StandardKernel();

kernel.Bind(x =>
    {
        x.FromThisAssembly() // Scans currently assembly
         .SelectAllClasses() // Retrieve all non-abstract classes
         .BindDefaultInterface(); // Binds the default interface to them;
    });

Default interface in this scenario means that if your interface is named IService, then the class named Service will be binded to it. However, the class SqlBasedService will not be binded and will fail to retrieve the implementation.

Binding single interface

IKernel kernel = new StandardKernel();

kernel.Bind(x =>
    {
        x.FromThisAssembly() // Scans currently assembly
         .SelectAllClasses() // Retrieve all non-abstract classes
         .BindSingleInterface(); // Binds the default interface to them;
    });

Binding single interface means that you are expecting to have one implementation per classes found. This would bind SqlBasedService to IService as well as Service to IService but would not bind SqlBasedService and Service to an IService.
