The InterfacingWithStdCOBOL.sln solution contains six projects. There are three pairs of projects, where each pair comprises a C# client console project and a COBOL project. Each client C# project makes a reference to its corresponding COBOL project so that it can use the implicit or explicit COBOL methods that are exposed.
The InterfacingWithStdCOBOL.sln solution is available in the Samples Browser and is available with the samples that are installed under %PUBLIC%\Documents\Micro Focus\Enterprise Developer\Samples, by default.
