With an incredible amount of appreciation gathered by Asp.net web development framework, it’s hard to imagine it fading away with the passing years. The narrow learning curve associated with Asp.net development is one of the key reasons behind the immense success of Asp.net. In other words, you actually don’t require a Ph.D. in computer science for being able to write the Asp.net code. Although creating web applications using Asp.net is fairly simple, even the veteran Asp.net developers are prone to committing minor as well as major mistakes. Through this blog, I’ll be focusing on five of the most common Asp.net development mistakes that increase the possibility of pitfalls within web development projects implemented with the help of Asp.net framework.
Mistakes- How they affect the smooth workflow within Asp.net web development?
Even after years of consulting on Asp.net projects, I’ve found that even the most proficient developers tend to make mistakes that affect the overall performance of the web application. In addition to this, there are other Asp.net development flaws that tend to interfere with the inhibit scalability of the application and cost the developers’ time and efforts in tracking down the bugs and other unexpected behaviors.
And now, it’s time to introduce 5 of the most common Asp.net development pitfalls that tend to litter the path of developing high-performing Asp.net web applications:
1. Avoiding the use of ‘using’ statement for disposing the objects
As a rule, whenever you use an IDisposable object, it is mandatory for you to declare and instantiate the same in a ‘using’ statement. This ‘using’ statement then calls the ‘Dispose’ method on the object and makes it jump out of scope as soon as the ‘Dispose’ method is called. A majority of Asp.net developers don’t use the ‘using’ statement and hence fail to ensure the calling of the ‘Dispose’ method in case of an exception that takes place while the methods are being called on the object.
2. Considering strings as non-immutable
Asp.net contains immutable strings. This means that once a string has been created, it’s value can’t be changed at a later point of time. This is something that isn’t been considered by the Asp.net developers, making them fall prey to unwanted hassles associated with the process of performing different string operations.
3. Syntax errors
Syntax errors are one of the most common errors taking place during Asp.net development. In other words, whenever you commit typing flaws in the code, the same are regarded as syntax errors. A possible and easy solution to the syntax errors is using the Notepad wherein every syntax error will be marked in the code editor. For example, if you’re using Visual Studio, then every syntax error that you tend to make will be underlined with a red zigzag line and if you mouse hover over the error, you’ll get to know the complete information about the same. The best part of Visual Studio is that in case an underlined syntax error get unnoticed, the user is informed about the same when he/she tries to compile the Asp.net application.
4. Keeping the roles un-cached
As a default feature, Asp.net 2.0 role manager doesn’t cache the roles data. Instead, it simply consults the roles data store every time there’s a need to determine which roles the user is associated with. The statement
<roleManager enabled=”true” /> included within the web.config files of Asp.net 2.0 applications has an adverse/negative affect on the performance of the respective applications. A simple solution to this problem is to configure the role manager to cache the roles data inside the cookies. In other words, you can replace
<roleManager enabled=”true”/> with
<roleManager enabled="true" cacheRolesInCookie="true" />. In addition to this, you can also utilize a variety of other
<roleManager? Attributes for controlling the role cookies’ traits including the duration for which the cookies should remain valid, frequency with which the role manager would go back to the roles database etc. In asp.net 2.0, role cookies are signed and encrypted by default. This reduces the security risk by an impressive level.
5. Not paying attention to the process of unhooking the event handlers after wiring them
Today, a large group of Asp.net developers don’t consider the process of unhooking event handlers important. While using C#, every time you register an event handler, you’re in a way creating a strong reference from the event source for the listener. So, unless you unhook this event, the listener won’t receive the garbage even if you don’t have any pointers directed to the listener. Therefore, as an Asp.net developer, it is quite essential for you to unhook the event handlers once they’ve been wired accurately.
Now that you’re aware about some of the commonly encountered problems with Asp.net development, the next step would be to take a closer look at your code and ensure to avoid making these mistakes. Asp.net is the perfect tool for creating slick and speedy apps. It’s your chance to leverage the best potential of Asp.net for delivering apps that impress everyone.
