I'm using Pega Robotics Studio 8.0.1053.0, while using script adapter it opens in an editable window. When opened it in another version of Pega Robotics Studio 8.0.1030.0, it opens up in a custom window where adding refernces and defining methods are easy. I want to know why this disparity in the 8.0.1053.0 version.
References are more intuitive with the new Script component. To add references, add them to your project references and use the 'using' keyword to import the namespaces as you would any other C# script. The old script component was lacking in a lot of features and has been upgraded with builds 8.0.1053 and higher.
