- Compile one or more C# files to a CIL executable:

`csc {{path/to/input_file_a.cs}} {{path/to/input_file_b.cs}}`

- Specify the output filename:

`csc /out:{{path/to/filename}} {{path/to/input_file.cs}}`

- Compile into a `.dll` library instead of an executable:

`csc /target:library {{path/to/input_file.cs}}`

- Reference another assembly:

`csc /reference:{{path/to/library.dll}} {{path/to/input_file.cs}}`

- Embed a resource:

`csc /resource:{{path/to/resource_file}} {{path/to/input_file.cs}}`

- Automatically generate XML documentation:

`csc /doc:{{path/to/output.xml}} {{path/to/input_file.cs}}`

- Specify an icon:

`csc /win32icon:{{path/to/icon.ico}} {{path/to/input_file.cs}}`

- Strongly-name the resulting assembly with a keyfile:

`csc /keyfile:{{path/to/keyfile}} {{path/to/input_file.cs}}`
