To build a COBOL project

Specify the build configuration.

Use the Configuration Manager to choose the build configuration to use for your project or solution.

Set properties for your projects such as, for example:

On the Application tab, specify the type of executable to build, such as a class library or an application
For some native COBOL project types, you can specify whether to build the source code to a single executable or produce individual executables for each COBOL program in your project.
On the COBOL tab, specify how to build the project, such as Compiler directives
On the COBOL Link tab of the properties for native projects, specify any link settings and the run-time system to link to
On the Dependency Paths tab, specify the copybook locations
On the Debug tab, choose the build configuration, such as Debug or Release

From Solution Explorer, add an application configuration file to a native project and use it to set any required environment variables and COBOL switches.

Build the project, by clicking Build > Build project name.
