What is an ASP.NET Provider?

问题:

What is the meaning of "Provider" in ASP.NET Provider? For example when we are speaking about AuthorizationRuleProvider, connectionStrings.providerName, ...?

回答1:

It's a design pattern: The Provider model. There is some good information in this SO Q&A as well: Designing loosely coupled components in .NET - Provider Pattern

回答2:

It's just a concrete implementation of an abstract interface. You can select an appropriate provider to fulfill the requirements of the interface at runtime.
