    I am receiving the following error when I try to compile:

    Error    31    OpenAccess Error: Telerik.OpenAccess: Updating SQL schema failed. Unexpected extension: db-column
    --> Assembly/namespace[psDataEntities]/class[psDataEntities.Basket]/field[_Categories]    psDataEntities   

    I have two entities: Basket and Category.  I just want a normal n:m relationship between them.  I have lots of other n:m relationsips that are working just fine.  Each side of the relationship works fine if they are just strings, but when I make them IList(of ...) then the error appears.

    Any thoughts

    Hello David Hufford,

     Can you try manually deleting the 'collection' mapping node under the field- categories (in the app.config file ) and map it again using the Forward mapping wizard?
