Validate Model State automatically in ASP.NET Core 2.0

A ModelState is a collection of name and value pairs submitted to the server during a POST request. It also contains a collection of error messages for each value. The Modelstate represents validation errors in submitted HTML form values. Model validation is the first statement in each controller action method to check for any error before moving forward. A familiar piece of code.

The IsValid property will be true when the values are attached correctly to the model AND no validation rules are broken in the binding process. However, writing this piece of code in every action method increases efforts, lines of code and repetitiveness. It would be appropriate to make model validation a reusable piece or even better would be to automate this process. This post talks about how to validate model state automatically in ASP.NET Core 2.0.

Create Petstore like Swagger UI for ASPNET Core WEB API

Create Petstore like Swagger UI for ASP.NET Core WEB API

Swagger doesn’t need an introduction as it is the world’s largest framework of API developer tools for the OpenAPI Specification(OAS), enabling development across the entire API life-cycle, from design and documentation, to test and deployment. Swagger is an UI representation of your RESTful API. It allows anyone — be it your development team or your end consumers — to visualize and interact with the API’s resources having none of the implementation logic in place. The Petstore (created by the swagger team) is a demonstration of the beautiful Swagger UI. You can easily integrate the Swagger in your application, but the sad part is you will get a different UI, not same as available @ Petstore. In this post, let’s find out how to create Petstore like Swagger UI for ASP.NET Core WEB API.

Previously, the developers have to build the application differently for each environment (Staging, UAT, Production) due to dependency on config file sections and the preprocessor directive applicable at compile time. It’s a time-consuming and painful process. ASP.NET Core takes a different approach and offers a new way to save developers from all this hassle. (more…)
