/target:winexe (C# Compiler Options)
The /target:winexe option causes the compiler to create an executable (EXE), Windows program.
The executable file will be created with the .exe extension. A Windows program is one that provides a user interface from either the .NET Framework library or with the Win32 APIs.
Use /target:exe to create a console application.
When specified at the command line, all files until the next /out or /target option are used to create the Windows program.
One and only one Main method is required in the source code files that are compiled into an .exe file. The /main option lets you specify which class contains the Main method, in cases where your code has more than one class with a Main method.
