Program Organization

C# programs are organized in namespaces
- Namespace can contain types and - recursively - other namespaces
Namespaces (and classes) in relation to files:
- One of more namespaces in a single file
- A single namespace in several files
- A single class in several files - partial classes
The mutual order of declarations is not significant in C#.
- No declaration before use.
When compiled, C# programs are organized in assemblies
- .exe and .dll files
