  • Is there a reason why you can't move navigation properties to the base type? Yes, there is not supported in V1 and there is little you can do to workaround this, esp when you want to get the derived types with nav properties in the result set.

    Hope this helps.

  • yes there is

    i have a table with one running number column and three FK columns that form a single key 

    for every row in the table , the key has 2 columns that are filled 

    one is the running number and the second is one of the FK columns

    there are three derived entities that associating to the relevent entity of the filled FK.

    anyhow , is there an date for the fix of this bug?
