Hello all, I'm coming from a java background and I just started learning C#. I'm wondering how C# organize their namespace physically on the computer?

For example, I have

[Folder] License (All *.cs classes "using" namespace License)

              XMLConfig.cs
              License.cs
              Encoder.cs
              Decoder.cs

[Folder] Authentication (All *.cs classes "using" namespace Authentication)

               SingleLogOn.cs
               Security.cs

I don't have visual studio .NET, so how do I compile these .cs files using "csc" and make them into a single dll file called "DeploySecurity.dll"?

Thanks a lot.
