Hello DevForce Support,
 
Would you please explain how to trigger the auto-generation of verifiers? Particularly StringLengthVerifier. Because I didn't find relevant settings in object mapper. And my problem is that, for instance not all tables with similar columns(string) will have verifiers generated for the properties in their Entity counterparts. Additionally for those generated, say if the maxlength is set to 250, when table updated and change max length to 150, this change won't be reflected into the latest design.cs, so verifier is still checking against length 250.
 
Thanks.
Viola

As for the second question: the Entity Framework is conservative in its changes to the Conceptual model, since it does not and cannot know what aspects of that model you want to parallel the Storage schema, and which you do not. You could have your own reasons for wanting the allowed string length in the application to be longer than the one persisted to the database. It would be an unusual case, but somewhere out there, there's somebody with a use case that needs it.

As for the first case, I'm unaware of circumstances where some string columns trigger the generation of string length verifiers and others do not.  I'll ask around.

If the columns are defined with a MaxLength of Max then the string length attribute should not be generated. Otherwise, they should appear. Let us know if you're seeing something different.
