The I in SOLID - The Interface Segregation Principle

'Does my interface look big in this?'

The Interface Segregation Principle can be expressed as: classes that implement interfaces should not be forced to implement methods they do not use. In other words: use small interfaces, not fat ones.

XAF Blog Series: Mastering Domain Components

DXperience 10.2 saw the release of the Domain Components technology, stalled as a result of issues involving XPO. However, this has not meant that the technology has been left idle.

Gary and the team have devised a series of blogs geared at introducing new Domain Components users to the technology, and allowing advanced users to master all of its intricacies.

The first post in this series deals with displaying two or more list objects where each object has a different default property. Simple? So you might think, but read on!

Remember to leave your feedback for Gary and the XAF team in the comments. They’re keen to know what additional Domain Components topics you think require exposure and explanation.
