You need .NET 6 SDK to build applications for .NET or the .NET 6 Run-Time System if you only want to run them.

The following table shows the architectures and the operating systems to which you can deploy .NET-targeted COBOL applications that you have published using Visual COBOL. The supported versions of the operating systems are the ones that Visual COBOL supports:
| Operating System | Architecture |
|---|---|
| Red Hat Enterprise Linux | x64 |
| SUSE Enterprise Linux | x64 |
| Ubuntu | x64 |
| CentOS | x64 |
| Windows Client | x64 |
| x86 | |
| Windows Server | x64 |
