Model Editor: Customize Application Model Visually

  • 2 minutes to read


To test the Model Editor with .NET 6+ projects, ensure that the following components are installed on your machine:

If you have shared XAF modules that must be reused in both .NET Framework and .NET 6+ apps, you can temporarily target .NET Standard 2.0 in these shared projects, as described in the following article: How to port an XAF shared module from .NET Framework to .NET Standard 2.0+.

The Application Model holds metadata that defines the application’s UI and behavior. That metadata is first formed from the business model code. Different modules can then apply their own changes. End users can also modify the Application Model to adjust their work environment.

You can examine and edit the Application Model on any of those layers. For this purpose, use the Model Editor.


This documentation section explains how you can invoke the Model Editor and describes its visual elements and capabilities.

Review the Customize Data Display and View Layout section of the XAF Tutorial for practical Model Editor usage scenarios.
