eXpand is the first open source project based on the DevExpress eXpressApp Framework (XAF). The eXpressApp Framework ships with DXperience Universal and can be evaluated free of charge (30 day trial) at: https://www.devexpress.com/ClientCenter/Downloads.

eXpand framework was started and is led by Tolis Bekiaris. Tolis has made a huge contribution to XAF over the years receiving great recognition from DevExpress and the whole XAF community. In April 2011 Tolis was honoured to be hired as Technical Evangelist for DevExpress frameworks!

The eXpand  Framework is an extension of XAF and operates within the Microsoft Public License (Ms-PL). Although XAF is not an open source product it can be purchased directly from DevExpress.

The eXpandFramework team have extended the capabilities of the eXpressApp Framework to include 61 cutting-edge assemblies containing tools and modules that target numerous business scenarios

The main idea behind eXpand is to offer as many features as possible to developers/business users  through a declarative approach (configuring files rather than writing code). Please go through each of the following brief descriptions and find out how eXpand can help you accomplish your complex development tasks with easy declarative programming. Below you can see some descriptions and screenshots of our basic modules (screenshots taken from eXpand FeatureCenter application that comes along with the download). In the folder Demos you can find a list of demos like XVideoRental, SecurityDemo, MiddleTier, Workflow and installation helper solutions for each module. 

Examples of those modules include (in the two right columns you can see the supported platform):

  2. Model Difference
    Extends XAF by adding great new features for example;
    • the ability to generate runtime members for your objects, 
    • creating Application/Role/User models in the database, 
    • storing your web cookies in the database, 
    • handling of external application models, 
    • combine end user modifications with application model, 
    • support for multiple models at design time,

  3. WorldCreator
    Creates dynamic persistent assemblies. The XAF user interface allows us to create an assembly without writing a single line of code. Advanced users can even use c# scripting and create new code generation templates.

  4. JobScheduler
    For those who are not familiar with the concept of job scheduling, here is some background information. Also, there is great Quartz tutorial, which provides an excellent introduction.

  5. DBMapper
    DBMapper has the same functionality as SqlDbMapper however is based on the powerful XPO . Thus  DBMapper module is capable of transforming into WorldCreator persistent classes the following list of databases: Access, Advantage, Adaptive Server Anywhere, Ase, DB2, FireBird, FireBirdSql, SqlServerCe, SqlServer, ODP,  Oracle, PersasizeSql, PostgreSql, SQLite, VistaDB  
  6. SqlDbMapper
    Can map any sql database into WorldCreator persistent classes and connect to it on the fly. This allows the user to take advantage of Xaf's strengths when mapping a legacy system with just a few clicks. Also we can use the dynamically generated code for your design time requirements

  7. Import Export Module
    Provides collaboration between a xaf application and another system by allowing you to create object serialization graphs. The complexity of a graph can be configured using either UI or design time attributes. Changing object keys and choosing serialization strategies are straightforward as seen in this screenshot.
