How to Troubleshoot Top Most Common Asp.net MVC Problems?

 

The latest release of asp.net Web forms by Microsoft had most .net developers who are waiting eagerly for new framework replacing the old classic asp scripting. Web forms made it really boring to keep page states track records which later bring in spaghetti code for several projects of website development.

With the introduction of MVC, web development was made easier since there were model, view, and controller structure. However, there were also complications and many .net programmers encountered numerous challenges while shifting to MVC.

In this article, we will talk about these common errors in asp.net and how developers of Asp.net Development Company in India troubleshoot them like expert.

• High response execution time

Request time in any application includes both the good code and optimized server configurations. Even a single poorly optimized component used in a web application can bring high execution time and time out. Issues related to performance are complex to address and resolve since the root cause count is any number of issues including – poorly written code and DB queries, low bandwidth, inadequate server resources, and even malfunctioning hardware.

During time out of application, a server admin take a quick glance at server resources with the help of Windows Task Manager on the server.

If the memory or Ethernet usage of CPU is seen, it could mean that there is a need to upgrade resources, but it could also happen due to poor code optimization.

• Slow loading of home page or first page

During initialization of web app in IIS, there are many server procedures fire up the application including cached resources, processing static content, the generation of dynamic data and a server response is received by the user. User requests can be seen as “hang” until initialization gets over, which could result in high bounce rate.

IIS 8.0 now include application initialization feature that helps enhance perceived site speed by initializing content proactively prior receiving the first request. The feature can be installed from the Server Manager tool.

Once the feature is added, developer can add configuration entries to applicationHost.config and web.config files.

• Over logging

Logging is a powerful tool that enables developers to identify issues that might have occurred at a certain period of time during app execution. It is important to address errors as they happen and collect contextual information of the application. However, there is a thin line between brief information and collecting error conditions and logging excessively.

There are two common issues:

1. Logging exceptions at multiple levels

2. Misconfiguration of production logging levels

Developers should log exceptions to understand issues that are happening in the app, but the common problem is to log exceptions at each layer of the developed app.

.Net loggers define the following logging levels – Off, Fatal, Warning, Error, Info, and Verbose / Debug.

• Code dependencies

Application development is a challenging thing done by most developers. They just don’t build the logic to satisfy their client’s needs, but also using the best libraries and tools to ease the job of development is what they do. Imagine building all of the logging management code your own, JSON parsing logic, or all of your own serialization libraries. You could create code for this, but why should you do that when there are the teams of open source developers who are already doing it for you?

There are other dangers for applying dependent libraries. You need to find answers to the following doubts:

1. Is the library well written and properly tested?

2. Is the use of library happening in the same way as the large numbers of companies are doing?

3. Is the way of using the library is correct?

It is important to use dependent libraries in right way.

• Showing custom errors

Error handling is important in every application. .Net default errors are more general and make users helpless. Developers can easily handle errors and provide custom message or handler with the use of Web.config or Global.asax files of the application.

Developers can take help of view to display messages and a controller to regulate the view.

• Underlying infrastructure issues

The application performs inside either asp.net or windows forms container, leverages the libraries to establish interaction with DB, runs within a CLR that uses an OS running on hardware. The same hardware is networked with other hardware which is hosting unique technology stack.

It is necessary to check the operating system and hardware used by app components and databases. See through the caches and check you are seeing high cache high rates.

Conclusion

Before deploying an application, it is necessary to test the app manually or with scripts. You can prevent some exceptions by just testing the app thoroughly; however, this won’t ensure that there will be no errors. Logging and monitoring these events will help reduce and mitigate their effects on the business productivity, application and the users.
