    **Debug Mode:**
    Developer use debug mode for debugging the web application on live/local server. Debug mode allow developers to break the execution of program using interrupt 3 and step through the code. Debug mode has below features:
   1) Less optimized code
   2) Some additional instructions are added to enable the developer to set a breakpoint on every source code line.
   3) More memory is used by the source code at runtime.
   4) Scripts & images downloaded by webresource.axd are not cached.
   5) It has big size, and runs slower.

    **Release Mode:**
    Developer use release mode for final deployment of source code on live server. Release mode dlls contain optimized code and it is for customers. Release mode has below features:
   1) More optimized code
   2) Some additional instructions are removed and developer can’t set a breakpoint on every source code line.
   3) Less memory is used by the source code at runtime.
   4) Scripts & images downloaded by webresource.axd are cached.
