On the surface, I suppose this is YAMVCVWFC (Yet Another MVC vs. WebForms Comparison). If this topic doesn’t appeal to you, or you’re sick and tired of this discussion then I encourage you to move on. I won’t be offended, promise. This post is here to serve as my living, breathing arguments for fighting for MVC and it will serve to highlight my major gripes with Web Forms. The motivation for this post came from an all-too-familiar IRC chat in #asp.net – for those of you unfamiliar with IRC, it’s a lot like the Twitter of the 90s. Fallacy: Web Forms does everything I need it to (01:29p) <webformsdev> 99.9999999999% of client requests, project requirements, etc etc, can easily and equally be done using webforms or mvc (01:30p) <webformsdev> webforms + jquery = does everything I need (01:30p) <@mattman> getting something...

I saw the following question asked earlier today -- the only context given was the code itself. Can anyone tell me what’s wrong with this Dim min As Integer = Integer.Parse(leavingTimeTextBox.Text.Substring(leavingTimeTextBox.Text.IndexOf(":") + 1, leavingTimeTextBox.Text.Length) -1 )? it shows me an exception index out of range exception: length and index must be within the range of the string, parameter name: length  so its five characters and on debug time : index is 2 so I'm starting from index 3 to length which is 5 -1 "4" It was clear that he looking to parse some sort of pre-defined time format, but just to be sure I confirmed it with him. While I could have helped this person resolve the question he asked about (the IndexOutOfRangeException), instead I took a step back to focus on what he really wanted to achieve. His immediate  problem was that he was too focused on the...

As a brief recap, the reason this post even exists is because the generated code from the EF4 designer does not properly suppress code analysis warnings. In that post, I mentioned that I would provide a proper T4 template and tutorial on integrating it into your EDMX model. This post details the steps to creating and customizing an Entity Framework 4 T4 template. T4 (the Text Template Transformation Toolkit) is the code generation technology built into Visual Studio. Thankfully, the EF4 designer has been enhanced to support customizable templates so that developers are free to change the code that is generated for your ObjectContext and Entity classes. To get started, I am assuming you already have an EDMX file that has been generated from your database. Beta Note These steps were written for Visual Studio 2010 Beta 2, so they may change slightly before RTM....

Update I have published the instructions and provided a template that can be used to properly suppress code analysis.   Starting a new project opens the doors for some great things. One of those things for me, was adherence to code analysis from the get-go. Visual Studio 2010 in particular has great Code Analysis Rule Set support allowing teams to carefully dictate which rules they wish to apply and suppress. Unfortunately, it wasn’t long before the decision to use Entity Framework 4 put a nice little wrench in my code analysis plan. (As an aside, I will blog more about my decision to use EF4 at a later date -- but long story short, it had to do with the large legacy database that we would be working with). Shortly after loading the existing database into the EDMX and compiling, I was greeted by nearly 1300 code analysis warnings, ranging from naming of properties to...

A very welcomed addition to the all-too-common File In Use dialog when trying to delete a file that a process has locked. As you can see from the screenshot, the dialog in Windows 7 finally tells the user exactly which process is preventing the deletion. No longer do I need Process Monitor from SysInternals for such a simple need.   Technorati Tags: Windows7
