Why the random names when I compile the classes to DLLS ?

I am playing with NDEPEND and it says to compile to DLL. So I use publish website and that creates the DLLs

But most of the files have a random name like

app_web_fgerger324.dll

How do I have them create names the relate to the classes that are compiled ?

Probably because it is a website and website assemblies are dynamically compiled. What you can do is use MSBuild to pre-compile a website.
