Benefits of Disable Debug Mode in ASP.NET

What activity happens on the server when we leave debug mode is true?

#1. It disables page timeouts
#2. It disables compiler optimizations to make symbols close to the actual source code statement
#3. To improve compilation time, it disables some of batch optimization
#4. Increase memory footprint of the application
#5. Disables caching of WebResources.axd (browser will download the associated script files again for every page),
#6. Disables compression of WebResources.axd resources
#7. Disables both page and JIT compiler optimizations


To enable or disable debugging, update the debug value in Web.Config accordingly

compilation debug="true/false"


But, if you want to enforce all site(same server) owner then make the below update in Machine.Config

 #1. This will enforce the 'debug' flag to false in every web.config on the machine.
#2. It will disable page output tracing and custom error pages to be shown to remote users instead of the real error messages.

* This value can only be set at the machine level, not at the application level.
* This setting overrides some application level security settings used for debugging

<configuration>
            <system.web>
                <deployment retail="true"/>
            </system.web>
</configuration>

Difference between Parse/TryParse/ParseExact/TryParseExact

Parse ===== //int.Parse("12.44"); //Exception : Above code will generate the exception "Input string was not in a correct format", just because you are trying to cast float/real value in int[Integer]. //Only it is parsing if your parameter value must match the desire type in which you are trying to parse. TryParse ======== //case #1 int.TryParse("14.55",out a); //case #2 int.TryParse("14", out a); //Above code(case 1) will return 'false', just because parsing operation gets failed and value for variable 'a' would be 'zero' //here consider 'a' is output type of parameter like we have in oracle/sql server(not exactly same but behavior is same). //if parsing get succeeded than it will return true and target variable (i.e. 'a') will have the...

Benefits of Test Driven Development (TDD)

1: Developer plays the role of user and developer while writing code, hence customer centric approach throughout the development 2: Reduces real time issues because of code written with end user mindset 3: Initially takes time but overall less-n-less debugging time 4: Identify cascading code break early or related change in other modules 5: Regression fix early 6: Help avoiding over engineering code which we don’t need actually 7: Avoid Scope Creep, helps in design and create high possibility of acceptance
