Quick ways to boost performance and scalability of ASP.NET, WCF and Desktop Clients
There are some simple configuration changes that you can make on machine.config and IIS to give your web applications significant performance boost. These are simple harmless changes but makes a lot of difference in terms of scalability. By tweaking system.net changes, you can increase the number of parallel calls that can be made from the services hosted on your servers as well as on desktop computers and thus increase scalability. By changing WCF throttling config you can increase number of simultaneous calls WCF can accept and thus make most use of your hardware power. By changing ASP.NET process model, you can increase number of concurrent requests that can be served by your website. And finally by turning on IIS caching and dynamic compression, you can dramatically increase the page download speed on browsers and and overall responsiveness of your applications.

Dynamically set WCF Endpoint in Silverlight
When you add a WCF service reference to a Silverlight Application, it generates the ServiceReference.ClientConfig file where the URL of the WCF endpoint is defined. When you add the WCF service reference on a development computer, the endpoint URL is on localhost. But when you deploy the Silverlight client and the WCF service on a production server, the endpoint URL no longer is on localhost instead on some domain. As a result, the Silverlight application fails to call the WCF services. You have to manually change the endpoint URL on the Silverlight config file to match the production URL before deploying live. Now if you are deploying the Silverlight application and the server side WCF service as a distributable application where customer install the service themselves on their own domain then you don’t know what will be the production URL. As a result, you can’t rely on the ServiceReference.ClientConfig. You have to dynamically find out on which domain the Silverlight application is running and what will be the endpoint URL of the WCF service. Here I will show you an approach to dynamically decide the endpoint URL.
