I\'ve built a entity framework model against a 2008 database. All works ok against the 2008 database. When I try to update the entity on a 2005 database I get this error.
Had a similar problem with 2012 vs. 2008. It can be solved with a BeforeBuild event using XmlPeek and XmlPoke:
If you dislike automated replacement, you can simply replace the XmlPoke task with an Error task.
