Delta Shell is currently being actively development. Preview version of the Delta Shell and various applications built using Delta Shell can be obtained in the Download section. Furthermore, new plugins can be developed using Delta Shell as a NuGet package. For more information check our developers tutorial on the Delta Shell Wiki.
Access to the Delta Shell source code will be available for open access in 2015/2016.
For a limited number of developers / beta testers worldwide, Deltares provides already access to the Delta Shell source code using the following link: https://svn.oss.deltares.nl/repos/delta-shell/.
Important note about use of commercial components in the current version
The current version of Delta Shell uses a number of commercial components which require a license for developers. If you plan to compile Delta Shell from scratch - you will need to obtain a license for the following components: DevExpress, TeeChart, PostSharp. We plan to replace these components by open-source alternatives before final release of Delta Shell.
