What is Attribute Routing in MVC?

ASP.NET Web API supports this type routing. This is introduced in MVC5. In this type of routing, attributes are being used to define the routes. This type of routing gives more control over classic URI Routing. Attribute Routing can be defined at controller level or at Action level like –

[Route(“{action = TestCategoryList}”)] — Controller Level
[Route(“customers/{TestCategoryId:int:min(10)}”)] — Action Level
