Best Practices for High-Performing ASP.NET Application Development

ASP.NET is a server-side framework of web application that has been designed to make the process of web development easier, especially for creation of dynamic web pages. This web application framework is much more influential and authoritative than the usual ASP. However, it is important to understand the usability of ASP.NET in building efficient, robust, and reliable applications.

To develop high performing applications through ASP.NET, you must consider integrating some best practices in the process. Let’s have a look at the aspects that you need to keep in mind during the application development process through ASP.NET.

Planning and Researching before Development is a Must: Researching and studying the beneficial aspects of ASP.NET for your development task is a must. It is important for you to understand the situation and examine the pros and cons of each single approach of this particular development environment and find out the best solution suited for a specific task. You can make use of layering to reasonably divide your application logic into data access layers, business, and presentation. This will allow you to develop a maintainable code and monitor the performance of the layers independently. Additionally, you can also lessen the code amount in the code-behind files to make scalability and maintenance better.

Deal with String Concatenation Properly: Improper use of String Concatenation can reduce the performance of an application largely. Concatenation of strings can be done in two ways. You can either consider adding a new string to the existing one, which might get expensive and time consuming or focus on using StringBuilder for the purpose.

Keep Away from Making Round Trips to the Server: You must always consider staying away from unnecessary round trips to the server. Have a look at the following tips to avoid the same:

• Integrate Ajax UI wherever possible: This would allow you to update only areas in the page that are to be changed without going for a complete refresh.
• Make use of Client Side Scripts: Validating client site can help you lessen the round trips for processing the request of the user.
• Use Page.ISPostBack: This would allow you to ensure performance of the logic of page initialization only during the first time load and not during client postbacks response.

ViewState Must be Saved only when Necessary: In ASP.NET, ViewState is automatically turned on. However, you might not require it every time during the development process and unnecessary use of the same can reduce the performance of your application. ViewState is primarily used by Server control on pages posting data to themselves and is a needless overhead on pages that can do without it.

Make Careful Use of Session Variables: Stay away from unusual data storage in session variables and ensure that you maintain a reasonable session time-out. This is important, as otherwise it might take up good space in server memory. Always remember that the data storage in session variables can stay on for long, even after closing the browser and maximum use of the same can reduce the performance of the server. If you do not need session variable in a particular application, it is always wiser to disable the same.

Make Use of Server.Transfer: If you are considering redirecting between pages of a same application, you must make use of the Server.Transfer method. This helps avoid needless redirection of client-side. Try considering Server.Transfer method, against Response. Redirect, whenever possible, provided the application remains same.

Choose Proper Data Viewing Control: It is necessary to determine the pros and cons of data viewing control, prior to using them in a specific application. For instance, you can make use of any of the three controls, DataList, DataGrid, and Repeater for displaying the data properly. It is necessary for you to find the one that would suit your application the best.

Optimize Exception Handling: When it comes to optimizing expensive loops, you must always use ‘For’ as a substitute to ‘ForEach’ in code paths that are performance critical. Additionally, you must also avoid depending on exceptions in the code. This is important, as exceptions reduce the performance largely and obstruct normal flow of the program.

Implementing the above-mentioned practices in the application development process through ASP.Net can make room for superior performance. Additionally, efficient use of paging and DataReader also enhances the performance of ASP.NET application development to a great extent. To implement best practices in application development, you need an ASP.NET development company as your development partner.
