Programmers generally use the Debug mode for debugging step by step their . Net project and select the Release mode for the final build of Assembly file (. dll or .exe). The Debug mode does not optimize the binary it produces because the relationship between source code and generated instructions is more complex.

What is debug and release configurations?

Visual Studio projects have separate release and debug configurations for your program. You build the debug version for debugging and the release version for the final release distribution. In debug configuration, your program compiles with full symbolic debug information and no optimization.

What is the difference debug and release?

Answer: The biggest difference between these is that: In a debug build the complete symbolic debug information is emitted to help while debugging applications and also the code optimization is not taken into account. While in release build the symbolic debug info is not emitted and the code execution is optimized.
