ASP.NET Session Expiration Redirect

2009-07-14T19:26:00Z

Unfortunately ASP.NET doesn't provide a nice out of the box solution for handling the session timeout gracefully. Everything expires behind the scenes and your user is left unaware of what has happened. Additional problems can arise if the user abandoned their browser in a state that you didn't code for, which can result in errors or exceptions taking place.

With this in mind I like to put a Session Expired page in place in my applications and pro-actively send the user there when their session ends....

C# Competency Test

2009-06-05T16:58:00Z

One of the companies I used to work for has a huge problem in keeping competent developers on board. They basically have a revolving door for anyone that is a decent software engineer and most of the employees that stay there long term can't go anywhere else - which is why they stay.

In honor of their high standard of excellence, I wrote the following C# competency test. If your organization is similar, feel free to pass it around and see if your co-workers can pass. :)

LINQ vs FOREACH vs FOR Loop Performance

2009-03-24T16:22:00Z

I made a blatantly stupid logic mistake the other day in a business logic layer method that I was writing and got the following exception: “Collection was modified; enumeration operation may not execute.” The problem what I was trying to remove an object from a collection while I was enumerating through it using a FOREACH statement. After I realized what I had done I solved the problem by populating a new collection with a little bit of LINQ.

After fixing my stupid mistake I went down a path of examining the performance differences between using LINQ, FOREACH and a standard FOR loop. I was surprised at the results. I knew that LINQ performance was slower, but I didn't realize exactly how much slower.

This is very import information for anyone who uses LINQ to be aware of:

Creating a SQL Exclusion Table Using LEFT JOIN

2009-03-17T17:42:00Z

For a current project I needed to create a table that contained a list of exclusions that should be filtered out from another table when a specific set of criteria were met. This is a pretty common scenario where you have a large table of data and you want to be able to provide the ability through a user interface for a user to filter the data using an exclusion list.

The Keys To Successfully Delivering Software

In this post I will share with you what I have learned that works well and what routinely causes failure.

How Has The Recession Effected You As A Developer?

2008-12-15T17:00:00Z

With all of the recession talk in the news, the daily massive layoffs that are taking place and the general doom & gloom feeling in the air I am very curious about how the recession has specifically effected developer's jobs. I have read many articles on CNN, MSNBC, etc. that have identified "computer programmer" positions as relatively safe jobs during this tough economic time. Have you found that to be true, are your jobs as developers relatively stable?

This blog posts provides a poll to vote on how the recession has specifically effected you as a developer.

WCF BasicHttpBinding with Windows Authentication & a 2.0 Client

2008-10-10T14:52:00Z

Windows Authentication is a great way to provide authentication security in your WCF services. With the WSHttpEndpoing and a .NET 3.0+ client Windows Authentication works right out of the box with WCF, everything is just peachy. However, if you want to use the BasicHttpBinding for .NET 2.0 client backward compatibility then it is going to require a bit of configuration for both the clients & server.

How To Have a Successful .NET Developer Interview

2008-09-30T20:48:00Z

I have been through a number of interviews now in my career and I have fared pretty well in many of them. While going through the interviews, I have created a mental list of what has worked well and what made a good impression on those conducting the interview. I have also made note of what impresses me (or turns me off) when I am the one conducting an interview.

Here are my top tips for success during your .NET developer interview.

Multiple WCF Endpoints & .NET 2.0 Clients

2008-08-21T21:12:00Z

I recently ran into a problem where .NET 2.0 clients were having problems connecting to the enterprise .NET 3.0 WCF web services platform that we built for internal use. We are hosting all of the web services in IIS6 (no upgrade to IIS7 anytime in the near future) and everything was working great for anyone running .NET 3.0 or later on their client apps.

The root of the problem was that we had only implemented one Endpoint, using the WSHttpBinding. This was great for any clients running .NET 3.0 or later, but this binding doesn't provide any backwards compatibility for clients running a framework earlier than .NET 3.0.....

ASP.NET Locale (State/Province, Country) LINQ User Control

2008-07-21T20:22:00Z

I just published my "Locale LINQ" user control...

Here are the basic features:
- Displays the corresponding States/Provinces based on the selected Country
- Includes a pretty exhaustive list of Countries & their associated States/Provinces
- Allows for an initial Country or State/Province to be selected via markup or server side code
- Caches the list of States/Provinces & Countries for great performance
- Based on an XML file containing the list of States/Provinces & Countries
- Uses LINQ for all of the data access & queries
