There are so many O/RM tools out there... What's Genome got to offer?
Before embarking on any hardcore marketing here, we'd like to stress that we recommend carrying out a simple sample implementation with the best couple of O/RM products that you have shortlisted. This should give you a sense of how mature they are and whether they meet your initial expectations as regards O/R mapping. It is also a very good way of investigating quality of support and documentation.
Now for the hardcore marketing...
Cutting edge technology for .NET
Genome was built for enterprise development and we have our track record, references and enterprise features to back up that claim.
Born and bred purely for the .NET Framework, Genome always keeps pace with the latest .NET technologies. A glance at our release history will show that Genome has kept at the forefront of developments in O/RM.
Not only do we make a point of hopping to the latest platform as soon as it is available, but we also make sure that Genome's set of features offers unique tools and capabilities to make your life as a developer easier. Genome's support of query encapsulation and reuse is a case in point and you can read more about this and other features in the Technical Reviewer's Guide. Or, if you would like more detail, browse Genome's online documentation.
How quickly can you count on getting custom extensions or fixes from other vendors? This is often a problem with very large corporations (ever requested a feature or hotfix from a giant like Microsoft?) as well as with open source (would you really want to branch and merge with each release just to implement custom features yourself?).
Genome is backed up by a dedicated, professional team working full time to evolve Genome further. This means that new developments, extensions and bug fixes are available promptly, not just when somebody in the community happens to find the time. The same goes for our support services (please read more about Genome support, the public support newsgroup and various other services that are available). Whether you need e-mail support, a code review, architectural advice or even custom features, the Genome team will deliver it within an acceptable timeframe.
In this context, you may also wish to read the sections on LINQ2SQL and open source alternatives.
