Clinical Study RWA Specifics

The DevExpress Clinical Study real-world application (RWA) is a multi-project solution. All solution project folders (marked with the "ClinicalStudy" prefix) are located in the C:\Users\Public\Documents\DevExpress Demos 20.2\Components\ASP.NET\CS\ folder, as shown in the image below.


In this folder, click the ClinicalStudy.sln file to open the solution file that contains all required projects.

The Clinical Study application consists of the following projects.

Project Name



For internal use only. This project is used to generate demo data. Demo data ships with the installation (the "~/ClinicalStudy.Site/App_Data/ClinicalStudyDb.mdf" file), so there is no need for it to be generated.


This project contains entity descriptions and interfaces for the ClinicalStudy.ModelBuilders project.


This project contains entities for the Clinical Study demo and service classes, which help to create valid entity hierarchies.


By design, the Clinical Study demo is available as both an online and offline demo (included as a part of the installation). Two different repository types are used - In-Memory repositories and SQL Server repositories.

  • In-memory repositories are used when the online demo is run from the DevExpress website;
  • SQL Server repositories are used when the demo is run on a localhost, which also requires Microsoft Entity Framework.


Unit-tests of repositories.


This project contains the MVC application itself, which uses DevExpress MVC Extensions. The project depends on other projects within the solution.

The MVC application is separated into two areas:

  • DataCapture - implements functionality for clinical trial management (for supervisors), and trial/patient data editing (for doctors);
  • Analytics - implements statistical, analytical, administrative and reporting functionality (for supervisors).

Project compilation requires an Internet connection to the server to download third-party libraries.


Unit-tests of the ClinicalStudy.Site project.


Contains theme sources. You can edit skins, images, and sprites. Changes will be applied after the project is rebuilt.
