Can you inject dependency through private constructor?
To answer your question, there is no way. by definition, private constructors are inaccessible by other classes. If you really need it to be a singleton, bind it in Singleton scope in Ninject. then Ninject will inject your repository into the singleton automatically the first time it’s requested.
What is a Parameterless constructor?
A constructor that takes no parameters is called a parameterless constructor. Parameterless constructors are invoked whenever an object is instantiated by using the new operator and no arguments are provided to new . For more information, see Instance Constructors.
Can constructors be Parameterless?

How does constructor Dependency Injection work?
In a nutshell, Constructor Injection uses parameters to inject dependencies . This is the most common DI, which is executed by supplying the dependency through the class’s constructor when instantiating that class. In addition, an injected component can be used anywhere within the class.
What is dependency injection and provide example?
In software engineering, dependency injection is a technique whereby one object supplies the dependencies of another object. A “dependency” is an object that can be used, for example as a service. Instead of a client specifying which service it will use, something tells the client what service to use.
Why to use a dependency injection container?
A Dependency Injection Container manages objects: from their instantiation to their configuration. The objects themselves do not know that they are managed by a container and know nothing about the container. That’s why a container is able to manage any PHP object. It is even better if the objects use dependency injection for their dependencies, but that’s not a prerequisite.
