/out (Visual Basic)
Specifies the name of the output file.
The compiler expects to find the output file following the /out option.
Specify the full name and extension of the file to create. If you do not, the .exe file takes its name from the source-code file containing the Sub Main procedure, and the .dll file takes its name from the first source-code file.
To set /out in the Visual Studio integrated development environment
Have a project selected in Solution Explorer. On the Project menu, click Properties. For more information, see Introduction to the Project Designer.
