Introduction to Deploying COBOL Applications to .NET Core

Attention: .NET Core on Linux is provided as an Early Adopter Program (EAP) feature only. It is being made available to allow you to test and provide feedback on the new capabilities. Be aware that file locking does not work in all instances, and may cause exceptions or the ignoring of file locks. We will continue the development of this feature and provide additional interfaces via patch updates and future releases. Please contact Micro Focus SupportLine if you require further clarification.

.NET Core is an open-source development platform that supports multiple operating systems. As such, a COBOL application that has been published for use with .NET Core can be deployed to any operating system that .NET Core supports.

The information in this section of the documentation describes how to deploy and run a COBOL application that has already been developed and published to target .NET Core. To develop and publish a COBOL application for .NET Core you must use Visual COBOL with Visual Studio 2019 version 16.4 or later.
