Hi Shahar,

DLLs are what IIS uses, it doesn't interact with the ".cs" files.
We will need information on the server configuration.
Are you using IIS or IISExpress? If it's full IIS, what is the "physical path" for the website?
The only DLLs in MonoX source are those in the "References" folder, so whenever you rebuild the solution, DLLs will be built.

For example, on my machine I have MonoX source in :
d:\MonoX-Release\5.1.40.5107\MonoX_Source_5_1_40_5107\
I create a new IIS website via IIS Manager and set the path to :
d:\MonoX-Release\5.1.40.5107\MonoX_Source_5_1_40_5107\Portal\
Whenever I build the solution from :
d:\MonoX-Release\5.1.40.5107\MonoX_Source_5_1_40_5107\MonoX.sln
IIS wil use my newly built DLLs from :
d:\MonoX-Release\5.1.40.5107\MonoX_Source_5_1_40_5107\Portal\bin\

Hope this helps,
Igor

ThanX but i've got the open source version, because i want to edit the functionality of the system.
i did not compiled the system yet!
i'm trying to develop new features, but i can't do that because the system is already precompiled.
how is it an open source system if the 'cs' files are just for the fun of it, and doesn't do anything?

As I mentioned before, the only precompiled files are those in the "References" folder, which are mostly third party libraries.
There are no DLLs in the source code package except those in the "References" folder. 
You can change every detail about MonoX with the source code edition, but you need to rebuild the solution for every change.

I will need detailed steps from "installation" to IIS setup.

Thanks

 sorry but you are exactly wrong.
this is exactly my problem.

look at the attached images, should it work?
well it is. (Although it should crash- there is no runtime error!)

and why doesn't this work?

This has nothing to do with MonoX. 

First picture (tsa)

It works because, I assume, Default.aspx.cs is still present and has the correct namespace.
If you look at the Page "Inherits" attribute it still points to "MonoSoftware.MonoX.Pages.Default" and not "MonoSoftware.MonoX.Pages.DefaultTestMeNow"

Second picture (tsa2)

This will not compile you need to put your code inside a method e.g. "OnInit".



>> and why doesn't this work?

I can't see any problems with this on my side (see the attached image).
I can't tell why it doesn't work for you, but I see you have deleted some of our code/markup;
 "</asp:PlaceHolder>" without opening tag is bad markup.
