Problem: Store some common data in a singleton or static class about your program in an object array, which you store in a class. It saves state between usages and stores some caches, and must be initialized only once and shared in many code locations. Making a new object each time would be expensive.

This month we have even more then in May in fact, we have almost tripple, we cover topics such as Deliver Next-Generation SOA Apps with Microsoft Robotics Development Studio, Get Started Building Silverlight 2 Applications, TypeTransmogrifier, Windows Mobile: Communicating with the Outside World and many more. Enjoy!

There are all sorts of different inline tags, and I haven’t found a place that explains them all in one place, so here is the quick and dirty…

The controls found in the AjaxControlToolkit fit perfectly into the ASP.NET programming model (as to be expected). You can configure the controls properties through the markup which in turn affects how the control's display and behavior on the client. Many of the control's properties support databinding so using the controls within a databound control like a ListView or a GridView is no big deal.

When I teach Silverlight 2, I stress an important lesson that I thought that we (as developers) had learned the importance of linkability of the web. Early usage of Flash was the first time I noticed this. A number of those sites would create nested functionality that never changed the URL. If the URL doesn't change, i can't bookmark it. Most Flash guys learned their lessons pretty quick, but now I am inundated with AJAX driven sites that try hard to not to do post-backs. That's cool, but if the URL doesn't change I can't link to it.

Through out the next few articles in this series, it is my intention to go over EVERY aspect of creating the site. For those of you who are new freelancers, these articles will hopefully prove to be an extremely helpful resource for you.

Our new free Silverlight datagrid beta 1 has just been released and is available for download immediately!

I previously wrote about taking CSS beyond a simple style library by writing HTML that’s easy to style. I’d like to go into one point in a bit more detail – avoiding class explosion by leveraging descendant selectors: You might think that really stylable HTML needs classes all over the place. That's not true, thanks to descendant selectors, which let you target elements inside a parent element. For instance, descendant selectors will let you style all > elements which appear inside a > with and id of "nav":

In this tip, I show you how to create a custom action result that you can return from an ASP.NET MVC controller action. This action result generates a Microsoft Excel Document from a LINQ to SQL query.

SQL injection can occur, as demonstrated above, when an application uses input to construct dynamic SQL statements or when it uses stored procedures to connect to the database. Conventional security measures, such as the use of SSL and IPSec, do not protect your application from SQL injection attacks. Successful SQL injection attacks enable malicious users to execute commands in an application's database. Common vulnerabilities that make your data access code susceptible to SQL injection attacks include

Some time ago I found very interesting project HAML. The idea behind this project is to make markup easy to read and fun to write. It very impressed me and I decided to implement View Engine for upcoming ASP.NET MVC Framework. Unfortunately (for me of course :)), it was already implemented by this guy. Not a problem! I simply decided to port Andrew’s work to the Castle Monorail (ASP.NET MVC elder brother) and extended Andrew’s work a bit.

This is the first edition of the monthly post that collects not to be missed articles from around the web that relates to .net. The amount of articles may vary from month to month but the quality will never. This month we cover topics such as Multi-Lingual Language Translations for ASP.NET, Dependency Injection using Spring.NET, How to Find Memory Leaks With CLRProfiler, WPF, PowerShell and many more. Enjoy!

It is a common practice to store time as UTC on the server and render it as local time based on the time zone the browser is running in. This blog post describes one simple approach to solving this problem.
