AddSingleton, AddScoped, AddTransient in .NET

Learn the key differences between AddSingleton, AddScoped, and AddTransient service lifetimes in ASP.NET Core Dependency Injection (DI). This video explains how these three methods control the lifecycle of services in your .NET Core applications, helping you choose the right lifetime for your services. AddSingleton creates a single instance of the service for the entire application lifetime. This instance is shared across all requests and components, ideal for stateless or shared resources like logging, caching, or configuration services. AddScoped creates one instance per HTTP request. Within the same request, the same instance is reused, but a new instance is created for each new request. Scoped services are perfect for request-specific data like database contexts. AddTransient creates a new instance every time the service is requested. Use this for lightweight, stateless services that require a fresh instance each time. Understanding these lifetimes is crucial for building efficient, maintainable, and high-performance ASP.NET Core applications.
