The .NET Library generator generates the components that execute .NET code in a DLL. After you select a DLL and a class or method that you want to use, this generator creates a custom component. This component can invoke and leverage code in the selected DLL. You can invoke the properties and methods of other components using the components that you created with this generator.
After you create custom components, you can use them in your workflow projects. You must import the custom components into your project before you can use them.
