thank you Dukc

it worked, i should adapt with this different naming style. (as 
comparing to C#)
[yesterday]
but today, when i went to create another project, it failed.
i get this message:

D:\ashit\documents\D\simpled>dub init simpled dlangui
Couldn't find package: dlangui.

it works without the "dlangui" option, but then when i execute 
run command:

D:\ashit\documents\D\simpled>dub run
Performing "debug" build using dmd for x86.
simpled ~master: building configuration "application"...
source\app.d(2,8): Error: module dlangui is in file 'dlangui.d' 
which cannot be
read
import path[0] = source
import path[1] = C:\dmd2\windows\bin\..\..\src\phobos
import path[2] = C:\dmd2\windows\bin\..\..\src\druntime\import
dmd failed with exit code 1.

this is the path i have extracted the dlangui files:

     D:\ashit\software\D Compiler\DlangUI\dlangui-master

how to define dlangui for DUB?
