Cherif,

This is correct, you can no *run* a DLL (if you mean this as "start the 
gdal15.dll") in any version of Visual Studio.
You need to add your own test program (.exe project) and attach its 
project to the solution, configure dependencies and set your test 
project as startup project.
If you don't know how to do it, refer MSDN and VS documentation:

All this is well explained in the VS documentation:

http://msdn.microsoft.com/en-us/library/aa909648.aspx

But please notice, you do need to set environment variables to be able 
to fully debug and test GDAL dll, but environment variables does not the 
first problem. You still need to create a project for test program (.exe 
application).

Another option but IMHO more difficult if you are not experienced with 
VS and debugging, as Tamas suggested, is to attach debugging session to 
a process started as .exe program, for example gdalinfo or ogrinfo.

In case you don't know how to configure and use Visual Studio debugger, 
I recommend to read MSDN:
