.NET COBOL applications require COBOL Server to enable them to run. COBOL Server provides support for .NET COBOL and also for native COBOL. The native COBOL support enables your application to interoperate with native COBOL.
Before you deploy your application, you must first install COBOL Server. This installs both the native COBOL and the .NET COBOL support. The installation process adds the .NET COBOL code support files to the Global Assembly Cache (GAC), and installs some files into the COBOL Server directory.
You can package your COBOL applications into a setup file, or you can copy the files manually. You can also deploy ASP.NET applications using the Publish Web Site tool in Visual Studio.
