size of the plugin dll

[123mobile]

Hi,

I am starting to write my own plugins, I am using visual studio 2005. I just compiled exdll and created exdll.dll.
The size of the dll is 356kb.
Also I try to compile other plugin source files and the size of dll is huge. Also at runtime the compiled dll gave me errors(eg in usrmgr.dll)
The size of dll of other people's dll is only around 10kb

Can anybody tell me why it is like this?
Thanks,
Prabhat.
