/recurse (C# Compiler Options)
Visual Studio 2012
The /recurse option enables you to compile source code files in all child directories of either the specified directory (dir) or of the project directory.
/recurse:[dir\]file
The /recurse option lets you compile source code files in all child directories of either the specified directory (dir) or of the project directory.
You can use wildcards in a file name to compile all matching files in the project directory without using /recurse.
This compiler option is unavailable in Visual Studio and cannot be changed programmatically.
