To use the command line to create a project for a COBOL application that is to be deployed to .NET you use the dotnet new command.
See the Related information for more information.
The dotnet new command can take a number of different options but the format for the most commonly-used options is as follows:
dotnet new template -lang "COBOL" --name project-name
where template is the type of project you want to create.
After running this command, the folder project-name is created, and in it are the various required project files and one or more template source files depending on the value you specified for template.
To see the possible values that you can specify for template, run the following command:
dotnet new --list -lang "COBOL"
Example:
To create a COBOL console application called COBOLConsoleAppForDotNet run the following command:
dotnet new console -lang "COBOL" --name COBOLConsoleAppForDotNet
