To wait or not to wait; that is the question! Whether or not to implement asynchronous processing is one of the fundamental issues that a developer must answer when invoking function calls across process boundaries. Given that the option to invoke an asynchronous call is available, the programmer has to weigh the relative ease of coding synchronous calls with its inherent drawback - when a synchronous call is made, the calling thread is blocked and has to wait until the function completes. In many instances, this is an acceptable shortcoming, as in the case when a program's logic flow should not continue until data is retrieved from a database. Asynchronous processing, on the other hand, allows more parallelism. A thread that initiates an asynchronous call is not blocked and can therefore do almost any computation while the method is in transit. The case for asynchronous processing becomes very compelling in the enterprise computing space where systems need to handle hundreds of thousands of function call requests and synchronicity may become a barrier to scalability.
Apparently some developers worry about what their sites look like and as a result they actually work with a graphic designer or layout artist (I'm not up on the politically correct title) to get it looking spiffy... who knew! ;) This is where code-behind really is a godsend. You just send the graphics person the Web Form portion of your page and they work with that. They never get to see (or mess with and break) the code that you've spent days working to get just right
In classic ASP, the Session object was held in process (as was everything) to the IIS process and therefore any crash to the IIS or apps pool being reset will cause the whole Session object being resetted. Hence this will make the Session objects not reliable at all and cannot be used to stored important data especially if your website is dealing with client login information or e-commerce type of website. In ASP.NET 2.0, new features has been introduced to make the Session objects more reliable and robust.
You produce high quality applications but you suffer from that your applications have much small market share if compared to lower quality competitive applications?
