    C# Project / VS Crashes on data source selection

    Hi,
    not sure if this is relevant to my code or is a visual studio issue. i have a c# project with entity frame work -sql database.

    when i select a datasource for an object, VS crashes with error below. i removed and refreshed EFW model from database.

    any clues what might be causing this

    I can barely read that. Please don't post screenshots of text. Post it directly as text.

    Based on the error message, it looks like you have code that is trying to access a table that doesn't exist.

    apparently somehow my entity model got corrupted, so i removed it and added again. I don't understand how code generation templates work, but it no longer have a constructor woth connection string parrameter and no definition for AddObject() entity methods.. Im lost
