/target:winexe (C# Compiler Options)
The /target:winexe option causes the compiler to create an executable (EXE), Windows program.
/target:winexe
Remarks
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.
Unless otherwise specified with the /out option, the output file name takes the name of the input file that contains the Main method.
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.
To set this compiler option in the Visual Studio development environment
Open the project's Properties page.
Click the Application property page.
Modify the Output type property.
For information on how to set this compiler option programmatically, see OutputType.
Example
Compile in.cs into a Windows program:
csc /target:winexe in.cs
