ReliableWcfService

A reliable wrapper around a WCF client proxy that provides seamless retrying, transient fault handling, and automatically closes or aborts the proxy as appropriate.

To use the ReliableWcfService, simply derive from the abstract ReliableWcfService class

public class DemoWcfService : System.ServiceModel.ReliableWcfService<ServiceReference1.IDemoService>
{
    protected override System.ServiceModel.ICommunicationObject CreateClientBase()
    {
        return new ServiceReference1.DemoServiceClient();
    }
}

Now you can host calls to the DemoService proxy within the DemoWcfService:

DemoWcfService demoService = new DemoWcfService();
string sampleData = await demoService.GetAsync(proxy => proxy.GetSampleDataAsync());

Transient Fault Handling & Retrying

WCF service proxies throw many different types of transient errors. ReliableWcfService automatically catches these transient exceptions and transparently retries.

• FaultException
• ChannelTerminatedException
• EndpointNotFoundException
• ServerTooBusyException
• TimeoutException

Automatically Closing & Aborting Proxies

WCF service proxies don't support the standard using() pattern. ReliableWcfService handles all of this for you!

The following vanilla WCF code will fail:

using (var proxy = new ServiceReference1.DemoServiceClient())
{
  string data = await proxy.GetSampleDataAsync();
}

Instead, you have to manually call Close() and Abort(), which adds unnecessary boilerplate:

var proxy = new ServiceReference1.DemoServiceClient();
try
{
  string data = await proxy.GetSampleDataAsync();
  proxy.Close();
}
catch(CommunicationException)
{
    proxy.Abort();
}
catch (TimeoutException)
{
    proxy.Abort();
}
