I will consume the Customer WCF Service which I developed in Part 1 on WS* Http Binding, you can implement the best security, transactions and many more things using this way. However, I will consume in a very simplistic way in this post. I assume that you have already deployed the WCF Service under IIS and have a working URL ready to be referenced and you are planning to use the customer WCF service in ASPX web Page.. [More]

As you know, the New Windows Communication Services (WCF) will replace the existing ASP.NET ASMX Web Services. So, it will be wise to plan it from today as how to transit in this new service model era. I first tried experimenting with WCF Service almost a year ago with the release of .NET 3.0 but VS 2005 and VISTA did work happily on my machine but now I like VS 2008. I revisited WCF again with the release of .NET 3.5, all the sample available on the web are either old or do not give enough information if you are looking for information as how to use this service in different way over different protocol, which can closely mimic a small real word example . So, I had to spend hours trying to find solutions and put the pieces together. So, I finally thought to create an example to help others who are facing the same situation. I have tried to closely mimic the ASMX Web Service uses, which I posted in my earlier post because most of us will be planning to convert from existing old one. With all the experiments I would give one key Mantra for WCF, dig the Config file specially to understand how to configure BEB (Binding, Endpoint and Behavior). This example deals with CRUD operation on Customer data which I used in earlier post. For the simplicity I am using XML file for the data source and will consume this service with WS* Standard, SOAP based XML POST, Plain Old XML (POX) and HTTP GET and POST. I believe these are the common uses along with TCP, named pipe and MSMQ.. [More]

In this post, the web service created in Part 1 will be consumed into a web page through Server Side Web Service Integration, Client Side SOAP XML HTTP Post, HTTP Form Get and Post. Following are the steps.. [More]

You must be wondering, that in WCF era ASMX Web Service! I wrote the first one 5 years ago and now trying to move them to WCF Service, but lot of companies have not even adopted the web service and some have only started adopting it recently, and now they realized that a new era has come. I will discuss my experiments & experiences with WCF in later post. However, I would like to post a simple Customer ASMX Web Service and then consume it by a ASP.NET Web Page via Server Side and then Client Side using direct SOAP based XML through HTTP Post. Later, I will create a similar WCF Service with exactly same methods and will access the data exactly same way. Remember this is not a simple HelloWorld Example, this Web Service deals with primitive data type as well as complex one. How far you would like to dive deep, it will be up to you.. [More]

You must be thinking that my web site is working great and generating no errors. But have you ever tried catching errors on Application_Error event in Global.asax, it catches all unhandled errors. Try applying the following code, and you will be amazed to see that your site is generating some errors which you were not even aware of. The following method will dump all the erros into a XML file which will be create on montly basis. Initially I was sending these errors to my email, but it is not easy to analyze all the data at once. XML file can be imported in Excel easily and you can fix the code which is generating more errors.. [More]

You can choose to create a XML file in which detail records are represented as Elements or Attributes only. It is wiser to use the best use of both, more use of attribute reduces the size of xml file and increases the speed over wire. Representation of data in Elements only XML file becomes heavier in file size thus slower the transmission. The only benefit is when you open this file in browser it is relatively easily to read. Following are an example for creating a file with same information in two different ways.. [More]

There are some situations especially in development or QA environment when you would to like ignore the SSL certificate. Generally this warning occurs when SSL certificate is either assigned to a different domain name, IP Address or self signed. You will most likely see the one of following error or warning messages when information is posted manually through Internet Explorer or FireFox browser.. [More]
