  1. POWhat would you use for a business validation layer?
    text
    copied!<p>In my project I need to create a business object validation layer that will take my object and run it against a set of rules and return either pass or fail and it's list of failure reasons. I know there are quite a few options out there for accomplishing this.</p> <p>From Microsoft:</p> <ul> <li><a href="http://www.google.com/url?sa=t&amp;source=web&amp;ct=res&amp;cd=1&amp;url=http%3A%2F%2Fmsdn.microsoft.com%2Fen-us%2Flibrary%2Fcc309509.aspx&amp;ei=LAGOSYrcN5CCNcTMiZIL&amp;usg=AFQjCNGYSsoNq_hV223GKaGvO0EMTfN4Pw&amp;sig2=AtQJwf8KrUATfYvTMD9q4g" rel="nofollow noreferrer">Enterprise Library Validation Application Block</a></li> <li><a href="http://www.google.com/url?sa=t&amp;source=web&amp;ct=res&amp;cd=1&amp;url=http%3A%2F%2Fmsdn.microsoft.com%2Fen-us%2Flibrary%2Faa480193.aspx&amp;ei=SAGOSfbtGpCCNbXMiZIL&amp;usg=AFQjCNFAKrvKAmkMkprSsL-YDtXcP5_m4A&amp;sig2=FHQuHQpcyQSxhJvM08ovtg" rel="nofollow noreferrer">Windows Workflow Foundation Rules Engine</a></li> </ul> <p>Open Source:</p> <ul> <li><a href="http://droolsdotnet.codehaus.org/" rel="nofollow noreferrer">Drools.NET</a></li> <li><a href="http://sourceforge.net/projects/sdsre/" rel="nofollow noreferrer">Simple Rule Engine(SRE)</a> </li> <li><a href="http://nxbre.wiki.sourceforge.net/" rel="nofollow noreferrer">NxBRE</a></li> </ul> <p>Has anyone had any particularly great successes or failures with any of these technologies (or any that I didn't list) or any opinions on what they feel is best suited for business rules validation.</p> <p><strong>Edit:</strong> I'm not just asking about generic validations string length &lt; 200, zip code is 5 digits or 5+4 but assume that the rules engine would actually be leveraged.</p>
