General Development Compatibility (ObjectARX/.NET)

ObjectARX and .NET applications are developed using libraries that are designed to work with specific AutoCAD releases.

When a new product is released, an application that was developed for an earlier release of the product might need to be updated. Updating an existing application might require you to do one or more of the following:

New versions of the programming libraries is released with each product release, not all applications must be compiled or modified to work with the latest product release. Some product releases are "binary compatible" with each other, this allows for an application written for an earlier release to work with a later release of the product. The following table lists which releases of the AutoCAD product are forward binary compatible.
