WCF alternatives

• ServiceStack
• Transport is http only: http://www.servicestack.net/overview.htm
• NServiceBus
• Default transport is MSMQ, but others can be plugged in
• Agatha
• Use WCF for transport
• Why not WCF: http://thatextramile.be/blog/2009/07/why-i-dislike-classic-or-typical-wcf-usage

When used on UI application, the code after "await" is executed by UI thread by default.  In Console application however, we need special treatments. See:

How to publish metadata when using TCP binding:
1. Inside app.config, create service behavior element (e.g. HelloServiceBehavior)
2. Refer the behavior from service tag (behaviorConfiguration="HelloServiceBehavior")
3. Add endpoint to the service to exchange metadata, use contract="IMetadataExchange".

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior name="HelloServiceBehavior">
                    <serviceMetadata policyVersion="Policy15" />
                    <serviceDebug includeExceptionDetailInFaults="true" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <services>
            <service behaviorConfiguration="HelloServiceBehavior" name="HelloService">
                <endpoint address="net.tcp://localhost:8080/hello" binding="netTcpBinding"
                    bindingConfiguration="" name="HelloService" contract="IHelloService" />
                <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
            </service>
        </services>

Comparisons: http://msdn.microsoft.com/en-us/magazine/cc164015.aspx

Note that System.Timers.Timer and System.Threading.Timer by default call your timer event handler on a worker thread obtained from the common language runtime (CLR) thread pool.

	System.Windows.Forms	System.Timers	System.Threading
Timer event runs on what thread?	UI thread	UI or worker thread	Worker thread
Instances are thread safe?	No	Yes	No
Familiar/intuitive object model?	Yes	Yes	No
Requires Windows Forms?	Yes	No	No
Metronome-quality beat?	No	Yes*	Yes*
Timer event supports state object?	No	No	Yes
Initial timer event can be scheduled?	No	No	Yes
Class supports inheritance?	Yes	Yes	No
* Depending on the availability of system resources (for example, worker threads)

ASP.NET background thread

http://haacked.com/archive/2011/10/16/the-dangers-of-implementing-recurring-background-tasks-in-asp-net.aspx

http://blogs.msdn.com/b/tmarq/archive/2010/04/14/performing-asynchronous-work-or-tasks-in-asp-net-applications.aspx

In v4.0 ASP.NET, we won’t unload the AppDomain until all requests have completed. In v2.0/3.5 ASP.NET in IIS 7 integrated mode, we also won’t unload the AppDomain until all the requests have completed.  In v2.0/3.5 classic mode, we will only wait until httpRuntime/shutdownTimeout has been exceeded before unloading the AppDomain, so long running async requests are vulnerable to being rudely aborted.  To work around this, you’d want the shutdownTimeout to be sufficiently long.
