    I have followed the examples using the open access dataadapter and am able to do crud on 1 table, how do I do this on a
    join table without writing code.  For my purpose the OA adapter allows rapid development with little or as it handle all the crud against
    the generate .rling class. but I cant seem to find an example to query and update without writing a linq query or update statement in code behind.  Thanks for your help.

    Hello Daniel,

    Actually you could map a join table to a persistent type and use it as a real entity. In order to achieve that goal you should do the following steps:
    - Select the join table under the Model Schema Explorer;
    - Press F4 to open the Properties grid;
    - Set the IsJoinTable setting to True;
    - Right-click on the join table and select Create a Domain Class;
    - Save the diagram;
    Hope that helps.

    Kind regards,

    Hello Damyan,
    I was trying the steps that you outlined here, but once I set the "IsJoinTable" property to true, then the "Create a Domain Class" option disappears from the context menu. am I missing something here?

    Hello Mulham,

    Firstly I want to apologize for the inconsistent answer in my previous post.
    Actually you should set the IsJoinTable to False in order to achieve that goal.
    Hope that helps.
