CSLA 3.8.4 to CSLA 4.3.14 removed functionality.

[prlprp]

Greetings, we have a product that uses CSLA an very early version. We are in the process of upgrading the CSLA version. I have found that between 3.8.4 and 4.3.14 some functionality was removed, well at least how this functionality is implemented. In 3.8.4 there is a Csla.Validation library/functionality, but in 4.3.14 this is missing. Is this functionality now implemented in another way in 4.3.14 or has it been removed all together? If it is being implemented another way can someone give me an example of how that is done. I have a few pics attached.


Thanks, Paul

Hi. I'm not sure what you are looking for exactly. Furthermore I'm not familiar with these versions but I think the validation stuff is still there but newly organized. You should find the whole business rules infrastructure in the Rules folder of your second screenshot.

The rules engine was completely rewritten in CSLA 4. That was the third (and last) big rewrite of the rules engine, though it has evolved from version 4 to 9 so it works with async scenarios and many other things.

Starting in CSLA 4, rules are defined by a class that implements IBusinessRule or IAuthorizationRule.

The "Using CSLA 4" book covers how this all works.

You can see the 4.3 code here:

The rules engine and related code is in the /Rules directory:
