I am unable to find any resources on this that resolve my issue. I'm quite new to COBOL and the dotnet ecosystem. I am on the personal edition where I've created a COBOL class library (.NET) and a C# console application (.NET). I referenced the class library project and implemented the function, but I get this error shown below.

Error

Hi Douglas,

In order for C# to call COBOL you must also add a reference to the MicroFocus.COBOL.Runtime assembly to the C# project, if you are using the .NET Framework or you must add the MicroFocus.COBOL.Runtime.Core package to the C# project if you are using .NET (Core)  projects.

For.projects that target the NET Framework right click on the C# project's references folder and select MicroFocus.Runtime under Assemblies->extensions.

For projects that target NET (Core), navigate to Tools->NuGet Package Manager-->Manage NuGet packages for Solutions and install the MicroFocus.COBOL.Runtime.Core package into the C# project. For more information on programming for .NET (Core) please see the documentation here:
