comment How to: Conditional Symbology in ArcMap
definition does not require flag field. So 1st layer where clause: agreements is not null, where clause of 2nd: agreements is null

Why it is not dynamic? The datasources of two layers should point to the same feature class/shapefile. So when you modify agreement field in this shapefile/feature class results of definition query change.

you can split parcel layer in two with agreement and without based on definition query and render them with different symbols

comment Is it a bad idea to hold references to ArcObjects inside business classes?
So I want to follow best practices in software development during refactoring this nightmare(I`m on a long way of studying).So to achieve loose coupling it is better to break application into layers and separate ArcGis API through DAL and utility classes and use some interchangeable storage of GIS specific data in domain model(like WKB)?

For now I cache both geometry & features references in my BO. BO themselves hold feature`s field valued in private fields and expose them through public properties. They also have some domain logic and preform CRUD operations on features.

Thanks the answer. I'm aware of managing objects lifetime in ArcObjects, and always try to release unused references :) I worry about threading issues in ArcObjects, may be caching references in BO is bad idea, as they may reference some kind of shared resource. Because I faced some kind of non repeated errors in ArcGis with geometry and TopologicalOperator - incorrect buffer results, sudden hangs.

comment How to merge several tables/feature classes into single geodatabase object in ArcObejcts?
George, thank you for such great sample! It is a good idea to implement custom GxObject. This covers almost all my needs, except providing the way for creating this objects in arccatalog through new menu. Is there any sample for such thing?

I thought that I could achive this by writing class and workspace extensions that implement standard ESRI geodatabase interafces. But I do not know wich of them shold I use.
