Understand OpenAPI document generation in ASP.NET Core |
|
If you are following the latest happenings in the ASP.NET space then you are probably aware that Swagger UI support has been removed from the default Web API project template. The default project template now simply provides support for generating OpenAPI documents. Of course, you can still use third party tools such as Swagger and Scalar to read the OpenAPI documents. |

Perform custom fluent validation in Blazor |
|
In the previous article we created a custom validation attribute to validate Blazor's EditForm. If you developed ASP.NET Core MVC apps before, you might have used FlientValidation library for validation instead of using validation attributes. Can we use FluentValidation in Blazor? |

Perform custom validation in Blazor |
|
Validating form data is one of the most common task in any web application. ASP.NET Core offers a set of validation attributes for performing model level data validations. Blazor apps can also make use of the same validation attributes. Some of the validation attributes include [Required], [StringLength], [Range], and [Compare]. At times you want to perform some validation not covered by these attributes. This is when you want to create a custom validation attribute. In this article we will discuss how that can be done. |

Use keyed services in ASP.NET Core |
|
A few years ago I wrote an article describing how ASP.NET Core DI container behaves when multiple implementations of an interface are registered. It's time to revisit the concept because .NET 8 has something better to offer -- Keyed Services. I am going to use the same example that I used in the earlier article. We will modify the example for .NET 8. |

Store connection string in Azure App Service and Azure Key Vault |
|
In the previous article you learned to deploy an ASP.NET Cor web app in an Azure App Service using two techniques. Recollect that we are storing the database connection string in the appsettings.json file. And we need to change it to match the production setup at the time of deployment. In this article we will discuss two better ways of storing the database connection string. Firstly, we will learn to store the connection string into the Azure App Service itself. And then we will store it in Azure Key Vault. |
