Asynchronous Calls at client-side

WCF offers all of these options to clients. The WCF support is strictly a client-side
facility, and in fact the service is unaware it is being invoked asynchronously. This
means that intrinsically any service supports asynchronous calls, and that you can call
the same service both synchronously and asynchronously.

In addition, because all of the asynchronous invocation support happens on the client side regardless of the service, you can use any binding for the asynchronous invocation.

Alternative to IValueConvert, QuickConverter

https://quickconverter.codeplex.com/ Quick Setup Steps Add the assembly reference to your project. This can also easily be done using  the NuGet package . Add the namespaces to Quick Converter that it will need to know about (before any xaml that uses it is loaded). e.g. In your WPF application's App.xaml.cs file: public   partial   class   App  :  Application { public  App() :  base () { // Setup Quick Converter. // Add the System namespace so we can use primitive types (i.e. int, etc.). QuickConverter. EquationTokenizer .AddNamespace( typeof ( object )); // Add the System.Windows namespace so we can use Visibility.Collapsed, etc. QuickConverter. EquationTokenizer .AddNamespace( typeof (System.Windows. Visibility )); } } Add the Quick Converter namespace to your xaml files so you can ref...
