Difference between a Debug vs Release

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:

    

• While in release build the symbolic debug info is not emitted and the   code execution is optimized.
• More optimized code
• Some additional instructions are removed and developer can’t set a breakpoint on every source code line.
• Less memory is used by the source code at runtime.
• Scripts & images downloaded by webresource.axd are cached.
• It has small size, and runs fast.

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:

• debug build the complete symbolic debug information is emitted to help while debugging applications and also the code optimization is not taken into account.

• Less optimized code

• Some additional instructions are added to enable the developer to set a breakpoint on every source code line.

• More memory is used by the source code at runtime.

• Scripts & images downloaded by webresource.axd are not cached.

• It has big size, and runs slower
