What is difference between bin and obj folder?

Question

What is difference between bin and obj folder? From which should I pick ddl for deployment?

Akhil Mittal · Answer

Bin is where the final compiled code is stored. Obj is where the compiler stores intermediate files...these are used for incremental builds (if you build a 2nd time, it doesn't rebuild the entire project and can reuse some of the stuff from the first time in obj to make the build faster). C++ makes use of obj much more than C#/Vb.Net Project reference references an existing project which is part of the solution. Dll reference simply points to a DLL of the file (if you pick DLL reference, make sure to reference the file from the bin folder (the better of two evils, in my opinion)). If you have the time and/or inclination, check out http://msdn.microsoft.com/library/de...l/tdlg_ch4.asp for more details on this last question. Personally, I prefer project references whenever possible (ie, when the source code is within my control).

Hi The obj folder holds object, or intermediate, files, which are compiled binary files that haven't been linked yet. They're essentially fragments that will be combined to produce the final executable. The compiler generates one object file for each source file, and those files are placed into the obj folder. The bin folder holds binary files, which are the actual executable code for your application or library Please reefer http://stackoverflow.com/questions/5308491/what-are-the-obj-and-bin-folders-created-by-visual-studio-used-for

Basically, the obj folder contains intermediate files created during compilation and the bin folder contains the final executable code for your application. Any private dlls which your application uses should be copied to the bin folder. Public dlls will probably have been installed in the global assembly cache (or GAC).
