The modularity is achieved using a Plugin architecture using Microsoft’s latest Managed Addin Framework (MAF). MAF is contract based Interface programming which helps in achieving late binding and domain isolation. The framework also supports independent versioning meaning the main program and plugins can be developed independently of each other. One of the main advantages is that software enhancements can be installed at Run Time without having to restart the application. The Das4NET framework is shown below. With the help of this framework a DAS application can share the same Engine but it will be defined based on the plugins that it has.
