![]() Hundreds puzzles to solve Puzzles based on LOGIC Auto fill feature HD Graphics New puzzles are added every week. In this blog I will explain how to use it. Nonograms, also known as Hanjie, Picross or Griddlers, are picture logic puzzles in which cells in a grid must be colored or left blank according to numbers at the side of the grid to reveal a hidden picture. Luckily there is a solution using the Unsafe.AsRef() method. This method returns a void which means that you have to modify the fields inside the struct, which is not allowed if the struct is readonly. The problem is caused by the ReadXml() method of this interface. A feature which Microsoft added to C# 7.2 a few years ago. This isn’t really hard, but it is harder when the struct is a readonly struct. For your own struct you have to implement the IXmlSerializable interface. The serialization and deserialization of those types are done by the XmlSerializer class. The primitive structs from Microsoft (bool, byte, short, int, long, double, decimal, etc.) don’t have this problem. For a class this is done automatically, but not for your own struct. ![]() Lees verder Implement IXmlSerializable in a readonly struct Most of my apps are free but there are Ads in it to generate some revenue. The apps have more than 5 million downloads and daily thousands of players. I have developed about 50 Windows (and Windows Phone) apps, some are very popular. I write my own training material so I need the experience. I use this experience for my trainings ( C#, XAML, ASP.NET and SQL). I create them because it is fun to do and it helps me to train my own skills. I write mainly XAML (UWP, WPF, WinUI and UnoPlatform) apps and only occasionally an ASP.NET MVC, WebAPI or Blazor WASM projects. I'm a Windows App developer more than a Web developer so I use different tools. In 2019 I wrote my own list, now it is time for an update because there are new tools I use. Many years ago Scott Hanselman wrote the famous Scott Hanselman Ultimate Tools List post. Lees verder Fons Sonnemans 2023 Development Tools List It is encourage you to use the new styles, as they better match the design direction of Windows. Starting with WinUI 2.6 there are new styles for most of the controls. Using styles, you can group a set of properties and assign them to specific controls or all controls of a specific type, and just like in CSS, a style can inherit (BasedOn) from another style. ![]() Styles let you set control properties and reuse those settings for a consistent appearance across multiple controls. You can customize the appearance of your apps in many ways by using the XAML framework like WPF, UWP, WinUI and MAUI. System controls need BasedOn Styling in WinUI
