In general you might also need an “assembly=” token to supply the location of the assembly but in this case it’s assumed to be the current project.įollowing this any name prefixed by m: is taken from the namespace of the current project - which is assumed in this case to be WpfApplication1. The “clr-namespace” is a special token which is interpreted to mean “get the namespace from the named CLR runtime”. So moving to the XAML editor we need to add a single line to the tag: In this case we need to import the namespace of the assembly that the XAML file is part of, i.e. You can import the namespace of any assembly and use namespaces to indicate exactly which class you are referring to. This is achieved by importing the class’s namespace into XAML. However first there has to be some way of making the link between the XAML document and the class definition. Now that we have our minimal class we can write some XAML to create an instance of it. Notice that as structs have a default parameterless constructor provided automatically by the system you can instantiate structs in XAML. It can have other constructors but these play no part in its working with XAML. Call it M圜lass: using System Īll that is necessary for a class to be instantiable by XAML is that it has a parameterless constructor and it can’t be a nested class. Right click on the project in the project window and select New,Add, New Item and finally C# class. Wpf colorconverter xaml code#You don’t need to modify any of the generated code but you do need to add a simple custom class with which to try out XAML. So let’s start with a simple WPF Application, MyProject say, using Visual Studio or your favourite IDE. We could start with a non-WPF project to prove how general XAML is we but this would waste a lot of time adding references and “usings”. To explain exactly what XAML is this article works with custom classes that have nothing to do with WPF so that we can find out about XAML in a completely general context that will help you understand all of its uses potential and current. Wpf colorconverter xaml windows#Its use in conjunction with WPF is just one of its many possible applications and indeed it has started to appear in other places – Windows Workflow for example and of course it is the UI design language for Windows Store apps i.e. If you keep this in mind then XAML is becomes a lot more transparent and easier to understand. XAML is a, mostly declarative, object instantiation language – that is it’s a way of describing using XML what objects should be created and how they should be initialized before your program starts running.
