Top 5 .NET Web Service Mistakes

In this article we’re going to discuss five common mistakes that enterprises make when developing web services. It’s important to note that these aren’t logic or syntax mistakes. There are no compiler errors to tell you that something is wrong and no exceptions will be thrown, at least not right away. The issues are architectural not technological. The key then is to avoid them from the beginning because dealing with them after your service is deployed will be much more difficult.

Web Page Source Transmitter: Get The Page As The Customer Sees It

Web applications without bugs - it is a myth.

Every developer has many problems when he should reproduce a customer's bug. Usually, the customer cannot provide enough information about conditions before an exception (field values he entered; page which was opened before an exception, etc.).

It will be very useful if the application can produce (restore) the source of the opened web page with the data entered, as it was before an exception and store it (e.g. into a database). In this case, the developer can get the source of the page (e.g. from the database), put it to an HTML file and open it in a browser. The developer will get a copy of the page as it was before the exception.
