What are the limitations of model binding attributes in ASP.NET?

Model binding attributes in ASP.NET can have several limitations, such as not supporting complex types directly, potential performance issues with large models, and challenges with validation when using custom attributes.

Can you explain how these limitations affect performance?

Certainly! When model binding attributes are used with large models, the binding process can become slower due to the overhead of mapping each property. This can lead to increased response times in web applications.

Are there any workarounds for these limitations?

Yes, some workarounds include using DTOs (Data Transfer Objects) to simplify models, implementing custom model binders, or using manual binding in the controller actions to have more control over the process.

What about validation issues? How can I handle them?

Validation issues can be handled by implementing custom validation attributes or using FluentValidation, which allows for more complex validation logic that can be applied outside of the model binding process.
