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 :
I create a new IIS website via IIS Manager and set the path to :
Whenever I build the solution from :
IIS wil use my newly built DLLs from :
Hope this helps,
