The D in SOLID - The Dependency Inversion Principle

Of all the principles in SOLID, the Dependency Inversion Principle is possibly the most important, and also possibly the hardest to convince someone to adhere to.

But consider the benefits if you manage it…

Framework Frenzy – Custom Functions & New SQL Operator Support

Custom functions are great, but previously you had to register them everywhere you wanted to use them - what a pain!

Thanks to the XAF team those days are long gone. You can now register once and use everywhere. Registering a function globally means you can use it everywhere you'd use a Criteria Operator. Not only that, you can even use custom functions with LINQ to XPO!

Speaking of XPO, the team have also been tweaking the SQL that XPO generates for SQL Server, by introducing support for the OUTER APPLY operator.

Since SQL Server can’t perform nested aggregates, nor aggregates on the columns specified in the group by list, this is great news.

We'd welcome your feedback on the team’s improvements. Let us know your thoughts in the blog comments.

Customizing the XAF User Interface

User Interface customization is a minefield. What may work well for you and your end-users, could be a total headache for others.

The problem is everyone has their own tastes and requirements, and a commercial application framework has to satisfy the most generic of cases.

In this webinar Gary shows how you can customize the default application templates in XAF if your tastes turn out to be somewhat mismatched with ours.
