Silverlight Technology

recently embarked on a new journey in my life on a relatively new technology for me. the thing is, for me. lol… faced quite some problems wif their wcf ria services where the async callback always fails. dunno sometimes is due to ip settings in the configuration file of the application, sometimes is due to the settings in the iis. but when all is checked and still fails, we r at a lost. how come .net applications becoming more and more difficult than java’s? microsoft has made quite gd efforts in upgrading their IDE, but for their server applications, it is still very difficult to configure. hope i can learn more of this technology and build on top of my .net framework knowledge…
