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.

यदू राजा आणि दत्तात्रेय अवधूत संवादातून शिकण्यासारख्या काही गोष्टी
तुम्ही जर दत्त भक्त असाल तर भागवत पुराणामध्ये आलेला यदू राजा आणि अवधूत दत्तात्रेय यांच्यामधील संवाद तुमच्या नक्कीच परिचयाचा असेल. यदू राजा एकदा एका ब्रह्मज्ञ अवधूताला पहातो. तो अवधूत एखाद्या बाळकाप्रमाणे काही कामधाम न करता आपल्यातच मग्न होऊन आनंदाने विचरण करत असतो. यदू राजाला तो एकलकोंडा अवधूत जडवत, उन्मत्त, पिशाच्चवत भासतो. आजूबाजूच्या भौतिक जगताची फिकीर नसलेल्या त्या अवधुताला यदू राजा त्याच्या ब्रह्ममय स्थितीचे रहस्य विचारतो.

Pro .NET 2.0 XML
(APress, April 2007)

XML is the de facto language for communication within and between distributed applications, whether they are on the Internet or a corporate network. XML is successful because of two strengths: it has a highly-structured human readable format and it can be transmitted as pure text. No matter how disparate applications and their architectures may be, text files can always be read, and therefore can accept XML data. This makes XML-based solutions advantageous over rival technologies like remoting. Pro .NET 2.0 XML is the first book to provide a complete solution to XML on the .NET Framework 2.0 including the new .NET 3.0 extensions that are being released in January 2007. It provides you with everything you need to know to take advantage of XML in every aspect of your job including integration with Windows Communication Foundation.

Professional XML for .NET Developers
(WROX Press, December 2001)

XML is now an established technology for the description and transportation of data, and has made a major impact on almost every aspect of software development. When Microsoft introduced the .NET Framework, they took advantage of XML wherever they could. No other technology is so tightly bound with .NET as XML, both at the developer level and underlying the whole framework. This book aims to give the reader enough information to be able to use XML from within the .NET Framework in the most efficient manner possible. It will explain in detail the usage of all the XML-related .NET Framework library classes for the manipulation, validation, transformation, and serialization of XML data, using both C# and Visual Basic .NET. It also looks at how the developer can utilize the full power of XML within the .NET Framework, for example, with the new XML capabilities of ADO.NET and ASP.NET. As is demonstrated, the .NET Framework itself uses XML, in configuration files, meta data, and C#'s XML code documentation mechanism, for example. This book is aimed at intermediate-level programmers who have started on their journey towards .NET development, and who want to see how to use XML within their applications to its best advantage. Basic knowledge of C# or Visual Basic .NET, XML, and XML related technologies (XSLT, XPath, and XML Schemas) is necessary.
