What are the differences between model binding attributes and parameter binding in ASP.NET?

What are the differences between model binding attributes and parameter binding in ASP.NET?

Model binding attributes are used to specify how data from HTTP requests should be bound to action method parameters, while parameter binding is a more general approach that relies on the framework to automatically bind data based on parameter names.

Can you give me an example of each?

Sure! For model binding attributes, you might use [FromBody] to bind a JSON object from the request body. For parameter binding, you could simply define a parameter in your action method, and ASP.NET will try to bind it from the query string or route data.

When should I use one over the other?

Use model binding attributes when you need more control over how data is bound, especially with complex types. Parameter binding is simpler and works well for basic scenarios.

Are there any performance implications between the two?

Generally, the performance difference is negligible for most applications. However, model binding attributes can introduce slight overhead due to additional processing.
