Use Endpoint Filters and Route Groups in Minimal APIs
ASP.NET Core Minimal APIs allow you to quickly create controller-less HTTP APIs with minimal dependencies. A minimal API typically has an endpoint URL and an endpoint handler. At times you want to intercept an endpoint handler so that you can add pre and post processing to the endpoint handler. That's where Endpoint Filters come into picture. When there are too many endpoints, it makes sense to group them using a common URL prefix. This is taken care by Route Groups. In this article we will examine both with a few examples.

Group Dropdown list items in ASP.NET Core
Displaying a list of options in a dropdown list or a listbox is quite common in ASP.NET Core forms. You can use the Select Tag Helper to render a <select> element and its options. If you want to display a large number of options to choose from, it would be better to group those options to make it easier for the end user to make the selection. In this article we will learn two ways to group dropdown list items.

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.

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.
