Hi Ranjithkumar,

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

for more details on this last question. Personally, I prefer project
references whenever possible (ie, when the source code is within my
control).

There is so very much for developers to learn. I suggest trying to learn the stuff we can actually use. If you have a need to understand things like that, then explain what you are trying to do so people can provide the best possible assistance.

hi,

The bin\ folder holds the results of the build: the binaries to distribute or archive, the XML documentation file, necessary dependencies and debug symbols.In other word Bin is where the final compiled code is stored.
The obj\ folder contains temporary files created during compilation. They are preserved so for an incremental build, the compiler can skip individual source files if they haven't changed and use the temporary files instead. That's faster :)
The obj folders would NOT be used for running the application - they are used for creating the end binaries in the bin folders.

hope this help.
