Hi Geert,

how about adding the following markup extension i use a lot when accessing services from xaml:

xaml example:


<catel:ServiceDependency x:Key="CultureManager" x:Type={x:Type Services:ICultureManager} />


Here is the code:

   public class ServiceDependencyExtension : MarkupExtension
        public ServiceDependencyExtension()

        public ServiceDependencyExtension(Type type, string name = null)
            this.Type = type;
            this.Name = name;

        public string Name { get; set; }

        public Type Type { get; set; }

         public override object ProvideValue(IServiceProvider serviceProvider)
            if (Environment.IsInDesignMode)
                return null;

            Contract.Assert(this.Type != null);
            return ServiceLocator.Instance.ResolveType(this.Type, this.Name);

Looks nice. The only downside is that it is hard to use methods inside bindings, but for properties, this is nice.

i use it for fast and uncomplicated xaml "service" property bindings only .... (never tried it with any methods ...)

What is the name? The ServiceLocator in Catel does not support it. Is it the property?

sorry i copied the wrong (older) code. you can simply dismiss the name property. it was for containers which support to resolve named service instances....

I already did and released a new beta via NuGet today.
